Answer 1

Respuesta:

x=6

x=−6

Simplifying

7x2 + -252 = 0

Reorder the terms:

-252 + 7x2 = 0

Solving

-252 + 7x2 = 0

Solving for variable 'x'.

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

Add '252' to each side of the equation.

-252 + 252 + 7x2 = 0 + 252

Combine like terms: -252 + 252 = 0

0 + 7x2 = 0 + 252

7x2 = 0 + 252

Combine like terms: 0 + 252 = 252

7x2 = 252

Divide each side by '7'.

x2 = 36

Simplifying

x2 = 36

Take the square root of each side:

x = {-6, 6}
