Question

x(b-3)+(b-3)

can someone explain to me how to factor these? I know its a simple question but its a bit hard for me

Answer 1

You can factor out the common factor of b-3 to get


x(b-3)+(b-3)

(x+1)(b-3)


So the answer is (x+1)(b-3)

Answer 2

x(b-3)+(b-3) = x(b-3)+1(b-3) = (b-3)(b+1)

Answer 3

Sure thing, pretend there is an invisible 1 after the plus sign
since you have b-3 in both parenthesis, it can be factored out, so part of the answer is (b-3)
Since you have an x and that invisible 1, the next part of the answer is (x+1)

so your answer is (x+1)(b-3)

Answer 4

You don't have to pretend the 1 is invisible, just add the 1 before the second binomial, then factor out (b-3)
