Please help me!! What are the solutions to this equation??

-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

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
