Question

How can you solve quadratic equation in one variable using extracting the square rots

Answer 1

Answer:

Key Strategy in Solving Quadratic Equations using the Square Root Method. The general approach is to collect all x2 terms on one side of the equation while keeping the constants to the opposite side. After doing so, the next obvious step is to take the square roots of both sides to solve for the value of x.

Answer 2

Given : quadratic equation in one variable.

To Find : How to solve using extracting the square roots. or Complete the square roots.

Solution: ax² + bx+ c = 0. (x + y)² = (x² + 2xy + y²) (x - y)² = ( x² - 2xy + y²) ax² + bx+ c = 0. Divide both sided by a. => x² + (b/a)x + c = 0. => x² + 2. x (b/2a) + c = 0.

I hope you will understand that please mark me as brainliest......if you agreed so...
