3a4 - 2a2 + 5a - 10 - 2a4 + 4a2 + 5a - 2 = a4 + 2a2 + 10a - 12 = a4 + (2a - 2)(a + 6)
2a + 3a + 4 = 5a + 4

9x + 91 is already simplified because there is nothing that is on the other side of the "equals" sign.
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
3a * * * * * Actually, it is 4a.
It is: 12x
6x plus 4y
11p+11
e times 5 = X
2a + 3a + 4 = 5a + 4
minus 4 plus 9 = 5, so 5x
4y -5

you can't simplify that anymore, you have to know what either x or y equals

13+-12--5 = 6
