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
Final solution are
