Question

The binomial (a 5) is a factor of a2 7a 10. what is the other factor? (a 2) (a 5) (a−2) (a−5)

Answer 1

An expression has numbers, variables, and mathematical operations. The other factor of the given binomial is a²+7a+10 except (a+5) is (a+2).

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

To find the other factor of the binomial a²+7a+10, we can write it as,

$a^2+7a+10\\\\=a^2+5a+2a+10\\\\=a(a+5)+2(a+5)\\\\=(a+5)(a+2)$

Thus, the other factor of the given binomial is a²+7a+10 except (a+5) is (a+2).
