Question

Please help! Which expression is equal to..?

Answer 1

A

Explanation:

Before we can add the 2 fractions we require them to have a common denominator.

Multiply the numerator/ denominator of the first fraction by x

Multiply the numerator/ denominator of the second fraction by (x + 3)

=
`(3x(x))/(x(x+3))` +
`((x-2)(x+3))/(x(x+3))`

Now simplify the numerator, leaving the denominator

=
`(3x^2+x^2+x-6)/(x(x+3))`

=
`(4x^2+x-6)/(x(x+3))` → A
