Solve 2x^2 − 8x = −7
kenny6666 [7]

Answer:

The answer to your question is below

Step-by-step explanation:

                                2x²  -   8x   =  - 7

Divide by 2

\frac{2}{2} x^{2}  - \frac{8}{2} x    = \frac{-7}{2}

Complete the trinomial

x^{2}  - 4x + (2)^{2}  = \frac{-7}{2} + (2)^{2}

Simplify

x^{2}  - 4x  + (2)^{2}  = \frac{- 7 + 4}{2}

x^{2}  - 4x + 4 = \frac{-3}{2}

Factor

(x - 2)²  =  \frac{-3}{2}

Get the square root

\sqrt{(x - 2)^{2}} = \sqrt{\frac{-3}{2}}

Simplification

               x - 2 =± \sqrt{\frac{3}{2}} i

      x₁ = 2 + \sqrt{\frac{3}{2}} i

       x₂ = 2 - \sqrt{\frac{3}{2}}
