Answer:
The greatest common factor of x4 and x³ is x³
Answer:
x = -1, x = 1
Step-by-step explanation:
Factor the equation. (It's a difference of squares, so we know the form will be (a-b)(a+b).)

Test this by FOILing it out, if you're unsure. This is something it can be good to memorize!
Set it equal to 0.

Separate the two parenthetical expressions by the Zero Product Property.

Solve for x!

No, they are not equivalent.
5(2x - y) = 10x - 5y and it is not equal to 15x - 5y.
(using distribution property)
-5+-12 is -17
For lack of a better metaphor, it's like digging a pit deeper than it already is.
I believe if that says three minus four times three minus five or three plus negative four times three plus negative five (same thing) then the answers should be positive two (2.)
