Question

I need help with this one math question please!

Answer 1

see explanation

Explanation:

Assuming the fractions are being multiplied

Factorise the denominators of both fractions

x² - 3x - 10 = (x - 5)(x + 2)

x² + x - 12 = (x + 4)(x - 3)

The product can now be expressed as

`(x-5)/((x-5)(x+2))` ×
`(x+2)/((x+4)(x-3))`

Cancel (x - 5) and (x + 2) on the numerators/ denominators, leaving

`(1)/((x+4)(x-3))` =
`(1)/(x^2+x-12)`
