Answer:
1.24x ^ 2 + 48x + 18
2.189 ^ 2 - 219 - 22
3. 4x ^ 3 + 12x ^ 2 - x - 4
4.2m ^ 2 - 3m - 18
5.2y ^ 2 + 11y + 28
Step-by-step explanation:
1.12x + 6
* 2x+3
36x + 18
=24x^ 2 +48x+18
2.6a- 11
X 3a+2
129 - 22
=189^ 2 -21a
3.3x ^ 2 - 1
x * 4
12 * 2 - 4
4x ^ 3 - x
=4x^ 3 +4x^ 3 +12x^ 2 -x-4
4. m + 3
m - 6
- 6m - 18
2m ^ 2 + 3m
5.y+4
Xy + 7
7y + 28
2y ^ 2 + 4y
=2y^ 2 +11y+28
