I'm assuming you are talking about polynomials.
For example, I have x^2 + 2x + 1, and I want to add 2x^2 + x + 2
Then the like terms here are:
x^2 and 2x^2, 2x and x, 1 and 2, they are quadratic, linear and constant, respectively.
A. multiply all the numbers together to find the possible outcomes
4 x 4 = 16
There are 16 different jacket-shirt outfits Ardell have.
They will not be the same color = 4 x 3
4 x 3 = 12
12/16 = 0.75, or a 75% chance they will not be the same color
hope this helps
