Write the following expression as a product of factors.

Question

(x+1)-y(x+1).

I have the answer sheet, but do not understand the stages to reach the answer. The answer is (x+1)(1-y) BTW.

Answer 1

This looks one of the steps you do when factoring by grouping. You just have to factor out the common term of (x+1) to get the answer that you showed.
