If 2x^2+2x=12, what is x?

x= 2

x= -3

Step-by-step explanation:

Solving as normal quadratic equation:

Roots are 2 and -3

Step-by-step explanation:

2x² + 2x - 12 = 0

Divide all the terms by 2 to simplify the terms

That's

x² + x - 6 = 0

Write x as a difference

That's

x² + 3x - 2x - 6 = 0

Factor x out of the equation

That's

x( x + 3) - 2x - 6 = 0

Factor out - 2 from the expression

x(x + 3) - 2( x + 3) = 0

Factor out x + 3 from the expression

That's

( x + 3)(x - 2) = 0

Hope this helps you
