Question

How many factors in the expression 8(+4)(y+4)(z²+4z+7)have exactly two terms?

Answer 1

In mathematics, a term is defined as a number or a variable, or a combination of both multiplied together.

Therefore, in the expression above, there are 4 factors, which consist of terms.  
However, the only factor in which there is two terms is (y + 4), because both y and 4 are separate terms.
