6-9x^2=-750 solve for x

Well I'm not positive but first you'd move 6 over and get - 744.

9x squared is 81x

81x = - 744

When rounded the answer is - 9.19, but the actual decimal is - 9.185185185185185

6 - 9x^2 = - 720

Move constant to the right side and change its sign

-9x^2 = - 750 - 6

Calculate the difference

-9x^2 = - 756

Divide both sides of the equation by - 9

x^2 = 84

Take the square root of both sides of the equation and remember to use both positive and negative roots
