Answer 2

Answer:

Simplifying

5x2 + -80 = 0

Reorder the terms:

-80 + 5x2 = 0

Solving

-80 + 5x2 = 0

Solving for variable 'x'.

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

Add '80' to each side of the equation.

-80 + 80 + 5x2 = 0 + 80

Combine like terms: -80 + 80 = 0

0 + 5x2 = 0 + 80

5x2 = 0 + 80

Combine like terms: 0 + 80 = 80

5x2 = 80

Divide each side by '5'.

x2 = 16

Simplifying

x2 = 16

Take the square root of each side:

x = {-4, 4}
