Hello!
1.) (x+2)(x^2-2x+4)
Multiply the x by each of the 3 terms in the second set of parens:
x^3 - 2x^2 + 4x
Multiply the 2 by the terms in the second parens:
2x^2 - 4x + 8
Now add both sets, combining like terms:
x^3 + 8
2.) (w+5)(W+12)
Use FOIL (front, outside, inside, last):
w^2 + 12w + 5w + 60
Combine the two w terms:
w^2 + 17w + 60
