I have no clue how to solve these, could someone help me?

Question

For questions 6-8, multiple the following polynomials.

7. 4a(a^2+7a+4)
A. 4a+28a^2+16a
B. 4a^3+28a^2+16a
C. 4a^3+44a
D. 44a^4

8. (2y-3)(3y-2)
A. 6y^2-13y+6
B. 6y^2-13y-6
C. 6y^2+13y-6
D. 6y^2+13y+6

Answer 1

2.D
Ur Welcome

Answer 2

well, Google distributive property
4a(a^2) = 4 a^3
4a(7a) = 28 a^2
4a(4) = 16 a
Now add :)
=======================
distributive property again
2y(3y-2) = 6 y^2 - 4 y
-3(3y-2) = -9y + 6
now add
6 y^2 - 13 y + 6

works every time

Answer 3

Please check, not D for 8 (or 2)

Answer 4

@ weekend, one of your answers is wrong.

Just giving somebody the answer does not help anybody, and will get you banned.

@ Ruby, we "solve" equations, you have no equations.
What you meant is to 'simplify'

Show some steps to show me what you did , so I can see where you went wrong.
