y squared-y-72 is an algebraic expression because it does not contain an equality sign.
2
y² - y - 6 = (y + 2)(y - 3)
(9y+2z)(y-3z)
it is (x-y)(x-y) :)
y squared-y-72 is an algebraic expression because it does not contain an equality sign.
xsquared minus x minus 72

y squared minus 9 (y*y)- 9 cannot be solved because there is no given value for 9.
y² - y - 6 = (y + 2)(y - 3)
(9y+2z)(y-3z)
it is (x-y)(x-y) :)
You have to put your heart into it!
There are no rational factors.
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
x^2 - y^2 - 4 is in its simplest form.
