Question

Brianne solved a quadratic equation. Her work is shown below, with Step 2 missing.

Answer 1

Given:

The given quadratic equation is

$3(x+4)^{2} = 48$

or, $(x+4)^{2} =16$

And

The roots are given: $x = -8 , x = 0$

To find the missing step.

Let us solve the equation.

$3(x+4)^{2} = 48$

or, $(x+4)^{2} = 16$

or, $x^{2} +8x+16 = 16$ [ eliminating 16 from both the side]

or, $x^{2} +8x = 0$

or, $x(x+8) = 0$

or, $x = 0, x = -8$

Hence,

The step 2 could be $x^{2} +8x = 0$
