1.) 4 (m+1)
2.) 3 (4t+2)
3.) 9 (2e-5)
4.) 2 (g+h)
5.) 3 (4c-2d)
6.) y (y +3)
7.) h (5 - h)
8.) 2p ( 4 - 2p)
9.) 2a ( 5 + a)

Each of the problems involves a MONOMIAL FACTOR and A BINOMIAL FACTOR !!

Distribution:
a(b + c) = a*b + a*c

5.) 3 (4c-2d) = 12c - 6d

6.) y (y +3) = y² + 3y

if you REALLY can't complete these exercises now, then you MUST go to your teacher for help, immediately !!

1. 4m+1
2. 12t+6
3. 18e-45
4. 2g+2h
5. 12c-6d
6. y^2+3y
7. 5h-h^2
8. 8p-4p^2
9. 10a+2a^2
10. 10t^2+6t

So ^2 means squared btw

This is extremely simple, so I'm just doing 2,4,6,8,10 and supposing you can then do 1,3,5,7,9.

#2.  12t + 6  #4.  2g + 2h  #6.  y^2 + 3y  #8.  8p - 4p^2  #10.  10t^2 - 6t.

4m + 4,  7t +8, 18e-45, 2g+2h, 7c-6d, y2+3y, 5h-h2, 8p-4p, 10a,2a2 10t-6t
