Answer: -1 and 1
Step-by-step explanation:
i gotchu, no worries!
first, move the constant to the right. then, you calculate that. then change the signs, and simplify the expression. (i can't type out square root signs, so thats why there's no work shown.)
then, evaluate it.
x^2 - 9 = -2^3
next, move the constant to the right.
x^2 - 9 = -8
next, calculate it.
x^2 = -8 + 9
simplify it.
x^2 = 1
finally separate the solutions.
x = 1
x = -1
472 to the nearest 100 is 500
