) (w-6)(4w^2+w-7)-1.2.3.4.7x2, 1,......
add or subtract

1.) (x^2+4x-1)+(5x^2+2)

2.) (7n^3+2n^2-n-4)-(4n^3-3n^2+8)

Find the product.

3.) (3x-1)(5x+1)

4.) (w-6)(4w^2+w-7)

-
1.) 6x^2+4x+1
2.) 3n^3+5n^2-n-12
3.) 15x^2-3x-1
4.) 4w^3+w^2-7w-24w^2-6w+42
4w^3-23w^2-13w+42

-
x2 + 4x -1 + 5x2 + 2
x2 + 5x2 = 7x2
-1 + 2 = 1
7x2, 1, x2

This was a example you can do others yourself because i think this is homework..:P
