Which of the following is a solution of x2 + 2x = -2?. (x + (-i + 1)), (x – (-i + 1)), (x – (-i – 1)), (x + (-i – 1))
The roots of the quadratic equation ax² +bx + c are:. (1) (-b/2a) + (√b² – 4ac)/2a = [-2/(2 × 1)] + (√2² – 4 × 1 × 2)/(2 × 6) = (-1) + √-4/2 = -1 + i
The two factors of the equation are: (x – (i – 1)) and (x – (-i – 1)). Hence from the given options,(x – (-i – 1)) is the solution.

Solve Quadratic equations x^2-2x-80=0 Tiger Algebra Solver [3]
Step-1 : Multiply the coefficient of the first term by the constant 1 • -80 = -80. Step-2 : Find two factors of -80 whose sum equals the coefficient of the middle term, which is -2 .
Step-4 : Add up the first 2 terms, pulling out like factors :. Add up the last 2 terms, pulling out common factors :
In other words, we are going to solve as many equations as there are terms in the product. Any solution of term = 0 solves product = 0 as well.

Quadratic equations are second-degree algebraic expressions and are of the form ax2 + bx + c = 0.. The word “Quadratic” is derived from the word “Quad” which means square.
By solving the quadratic formula x2 – 2x – 4 = 0, we get solution as x = 1 ± √5.

What is the positive solution to the equation 0 = -x2 + 2x + 1?. ⇒ Multiplying by -1 on both sides, we get x2 – 2x – 1 = 0
As we know that coefficient of x2 is a, coefficient of x is b and the constant term is c.. On finding the square root, we will have two values of ‘x’.
Thus, the positive solution to the equation –x2 + 2x + 1 = 0 is x = 1 + √2.. What is the positive solution to the equation 0 = -x2 + 2x + 1?

Changes made to your input should not affect the solution:. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
Step-2 : Find two factors of -15 whose sum equals the coefficient of the middle term, which is -2 .. Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 3
Add up the last 2 terms, pulling out common factors :. When a product of two or more terms equals zero, then at least one of the terms must be zero.
Quadratic equations, it’s… Step-by-Step Math Problem Solver [8]
Quadratic equations, it’s applications and other type of equations. As mentioned earlier, an equation of the form ax + b = 0 is a linear equation
(Why is the restriction a!=0 necessary?) A quadratic equation written in the form ax^2+bx+c=0 is in standard form.. The simplest method of solving a quadratic equation, but one that is not always easily applied, is by factoring
The next example shows how the zero-factor property is used to solve a quadratic equation.. By the zero-factor property, the product (3r -1)(2r + 3) can equal 0 only if

The Quadratic Formula [10]
· Write a quadratic equation in standard form and identify the values of a, b, and c in a standard form quadratic equation.. · Use the Quadratic Formula to find all real solutions.
· Compute the discriminant and state the number and type of solutions.. · Solve application problems requiring the use of the Quadratic Formula.
If you complete the square on the generic equation ax2 + bx + c = 0 and then solve for x, you find that . This formula is very helpful for solving quadratic equations that are difficult or impossible to factor, and using it can be faster than completing the square

This approach to solving equations is based on the fact that if the product of two quantities is zero, then at least one of the quantities must be zero. In other words, if a*b = 0, then either a = 0, or b = 0, or both
The idea behind completing the square is to rewrite the equation in a form that allows us to apply the square root principle.. The 9 added to both sides came from squaring half the coefficient of x, (6/2)2 = 9
Solve x^2 + 2x -3 = 0 [12]
We can solve quadratic equations by factoring and using the zero product property, which states that if two expressions multiply to give 0, then at least one of the expressions must be equal to 0. Solving quadratic equations in this way takes a few straightforward steps.
The solutions to x2 + 2x – 3 = 0 are x = -3 and x = 1.. To solve a quadratic equation by factoring, we use the following steps:
Find how to factor quadratic trinomials and discover their standard form. See quadratic trinomial examples, and find how to solve them.
