Okay, can you just show me how to do the first problem? lol
It's x raised to the 3rd power plus 1. This (^) means raised to the ___ power
Nevermind I figured it out, lol. It's "factoring cubes" but heres how you would do it, just in case anyone else finds this question
x^3 + 1 = (x)^3 + (1)^3 = (x+1)(x^2+(x)(1)+1^2 answer: = (x+1)(x^2+x+1)
What are you trying to do? Solve for X? If so, do it like this.
X^3 + 1 is essentially X^3 + 1 = 0
So subtract 1 to get it onto the other side. (X^3 = -1)
Then, cube root X^3 and also cube root -1
So the answer is X = -1
