Question

Factorise:x2-3x-40 find this answer fast​

Answer 1

This trinomial is in a special form that can be

factored into the product of two binomials.

So we set up two sets of parenthses.

As the first term, we have the factors of x², x and x.

For the second term, we have the factors of -40 that add to -3.

In this case, these factors are -8 and +5.

So our answer is (x - 8)(x + 5).
