Answer and Step-by-step explanation:
12.[p4-7p2-32p-15]/[p-4]
p*p*p*p-7*p*p-32p-15/p-4
4p-7*2p-32p-15/p-4
4p*2p-32p/p-7-15-4
8p-32p/p-7-15-4
8p-32p-26
-24p-26
11.[x4-2x3-29x2-43x+8/[x-7]
x*x*x*x-2*x*x*x-29*x*x-43x+8/x-7
4x-2*3x*-29*2x-43x+8/x-7
4x*3x*2x-43x/x-2-29+8-7
24x-43x/x-32
-19x-32
10.[2x3-14x+10/x/3]
2*x*x*x-14x+10/x/3
2*3x-14x+10/x/3
2*10/3*3x-14x/x
20/3*3x-14x
20/3*[-11x]
9.[m3-12m2+33m]/[m-5]
3m-12*m*m+33m]/[m-5]
3m*2m+33m/m-12-5
6m+33m-17
39m-17
Just use the same principle to get the rest of the two questions[I can't see them clearly]
