Question

What is the first step in solving the quadratic equation -5x^2+8=133?

Answer 1

Answer:

a) subtracting '8' on both sides, we get

                                      - 5 x² + 8-8 = 133-8

                                        - 5 x²  = 125

b) The solution is x = 5 i

Step-by-step explanation:

Explanation:-

Step (i):-

Given quadratic equation  - 5 x² + 8 = 133

subtracting '8' on both sides, we get

                                      - 5 x² + 8-8 = 133-8

                                       - 5 x²  = 125

Step(ii):-

dividing '-5' on both sides, we get

          $\frac{-5 x^2}{-5} = \frac{125}{-5}$

            x²  = -25

            $x = \sqrt{-25}$

            x = 5 i
