Question

Multiply the two binomials and find the value when x= 1, y = -1 and z = 2
(xy + yz) by (xy - yz)​

Answer 1

Answer:

Another special product is called the difference of squares, which occurs when we multiply a binomial by another binomial with the same terms but the opposite sign. Let's see what happens when we multiply ( x + 1 ) ( x − 1 ) \displaystyle \left(x+1\right)\left(x - 1\right) (x+1)(x−1) using the FOIL method.
