I'm multiplying polynomials and am a little confused on how to do (x+10) 2 [the two is supposed to be squared but I can't get the two at the top to represent squared in this post]. What are the steps?
Now, I'm going to multiply the x in the first bracket by everything in the second bracket, and then do the same with the 10 in the first bracket. (x+10)^2 = (x+10)(x+10) = x*x + 10x + 10x + (10)(10)
Collecting like terms and = x^2 + 20x + 100
I've included a picture that tries to show exactly where each term comes from.
