You need to make the right side = 0
To do this you subtract 10 from both sides of the equation:-
x^2 + 6x + 9 - 10 = 10 - 10
x^2 + 6x - 1 = 0
Cubed means you have to multiply it by the other number like an exponent so that means the answer is z3
R u sure there Is no more to the question? I feel like there is a missing number somewhere :)
