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

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).

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
