SOLVE PLEASEEE! (y+8)^3

OpenStudy (anonymous):

It's a triple root with only 1 real x intercept at x=-8.

OpenStudy (anonymous):

sorry, y=-8

OpenStudy (anonymous):

Do you want the steps?

OpenStudy (anonymous):

If so, take the cube root of both sides. y+8=0 y=-8

OpenStudy (anonymous):

its for a math hw, like the answer there telling me it is y^3+24y^2+192y+512

OpenStudy (anonymous):

Well, to get that answer, all that you have to do is expand.

OpenStudy (anonymous):

i just dont know how to get the answer, can you help me solve this one ? (z+9)^3

OpenStudy (anonymous):

Do you want the expanded form?

OpenStudy (anonymous):

OpenStudy (anonymous):

z^3+27z^2+243z+729

OpenStudy (anonymous):

All what you are doing is expanding.

OpenStudy (anonymous):

Do you want steps?
