Question

Simplify 15(x - 4)(x -1)-3(x + 4)(x - 1) with steps

Answer 1

Answer:

12(x-1) (x-6)

Step-by-step explanation:

15(x - 4)(x -1)-3(x + 4)(x - 1)

We can factor out a 3 from both terms

3 ( 5(x - 4)(x -1)-(x + 4)(x - 1))

We can also factor out (x-1)

3(x-1) [5(x - 4)-(x + 4)]

Distribute inside the brackets

3(x-1) [5x-20 -x-4]

Combine like terms

3(x-1)[4x-24]

We can factor out a 4

3(x-1) 4[x-6]

12(x-1) (x-6)
