the question is below

Step-by-step explanation:

Simplifying

4x2 + -20 = 556

Reorder the terms:

-20 + 4x2 = 556

Solving

-20 + 4x2 = 556

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '20' to each side of the equation.

-20 + 20 + 4x2 = 556 + 20

Combine like terms: -20 + 20 = 0

0 + 4x2 = 556 + 20

4x2 = 556 + 20

Combine like terms: 556 + 20 = 576

4x2 = 576

Divide each side by '4'.

x2 = 144

Simplifying

x2 = 144

Take the square root of each side:

x = {-12, 12}
