It is not clear what you want to solve for.
You have to put your heart into it!
y squared-y-72 is an algebraic expression because it does not contain an equality sign.
y² - y - 6 = (y + 2)(y - 3)
it is (x-y)(x-y) :)
There are no rational factors.
y2-y-72 is an algebraic expression that can be factored as: (y+8)(y-9)
The factoring is as follows: x2 - y2 = (x + y) * (x - y)
it depends,if y = 0 the answer is -12 if y = 5 then the answer is 368
Add 2.9 to both sides. y = 8.2
