## jvg1231 2 years ago SOLVE PLEASEEE! (y+8)^3

1. zordoloom

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

2. zordoloom

sorry, y=-8

3. zordoloom

Do you want the steps?

4. zordoloom

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

5. jvg1231

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

6. zordoloom

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

7. jvg1231

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

8. zordoloom

Do you want the expanded form?

9. jvg1231

10. zordoloom

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

11. zordoloom

All what you are doing is expanding.

12. zordoloom

Do you want steps?

13. jvg1231

THANK YOU! I REALLY APPRECIATE IT!

14. zordoloom

So no steps needed?

15. jvg1231

do you mind helping me with my last one?

16. jvg1231

nope thats it. just the expanding.

17. zordoloom

18. jvg1231

(2r-3t)^4

19. zordoloom

16r^4-96r^3+216r^2t^2-216rt^3+81t^4

20. jvg1231

THANK YOU VERYYY MUCH!

21. zordoloom
