Answer:
ab(ab + 20)
Step-by-step explanation:
Because we see both terms have at least one ab in it, we can factor out ab and get ab(ab + 20). However, because ab^2 does not have any coefficient, there is nothing more to factor out. Thus, ab is your greatest common factor, or GCF.
Hello!
The y intercept of the parabola is when one of it's function's hits/intersects the y axis. The y intercept of the parabola y = x^2 is (0,0).
You may be wondering where is that, and why is it there. Y = x^2 is a parent function.
Check the image below for better explanation from me.
(0,0) = y - intercept
