Question

How do you factor the expression `12(x – 5) + 7x(x – 5)`?

Answer 1

(x -5)(12 +7x)

Explanation:

There is a common factor of (x - 5) in both terms which can be taken out.

Taking (x-5) as a common factor in 1st term leaves 12

Taking (x-5) as a common factor in 2nd term leaves +7x

hence : (x-5)(12 +7x) is the factorised expression.
