Using the distributive property of multiplication over
addition, we can factor as in x2 + xy = x1x + y2. Use
the distributive property and other multiplication properties
to factor each of the following:
47.99 + 47
(x+1)Y +(X+1)
x^2y+z^x3

Do you mean x^2y + x^3*Z? If so,
x^2(y+xz).
See 2nd post below for solution to other 2 problems.
