Question

Factorise the following expression using grouping and use binomial products to simplify.

11x - 55 - 5a + ax

Answer 1

Answer is below. I have grouped it.

Explanation:

=(11x-55) + (-5a+ax)

=11 ( x - 5) +a ( -5+x)

= 11(x-5)+a(x-5)

(11+a)(x-5)

(x-5)(11+a)

Answer 2

11x-55-5a+ax

11(x-5)+a(x-5)

(11+a)(x-5)

Explanation:

First you factor out the common factors

for(11x-55) is would be 11 as both of these figures are the multiple of 11

for(ax-5a) the common factor is a which will be factor out

Then after doing the process you will get

11(x-5)+a(x-5)

then factor out(x-5)which will give you

(11+a)(x-5)
