Question

Simplify the following expression show your work PLEASE HELP

Answer 1

add the fractions inside the brackets

\[\frac{x(x+4) + 6(x -4)}{(x+4)(x-4)} \]

factorise the divisor

\[\frac{3}{2( x-4)(x+4)}\]

when dividing by a fraction invert and multiply

\[\frac{x(x+4) +6(x-4)}{(x-4)(x+4)} \times \frac{2(x-4)(x+4)}{3}\]

remove the common factor of (x-4)(x+4)

leaves

\[\frac{2( x(x +4)+6(x-4))}{3}\]

simplify the numerator

\[\frac{2x^2 + 20x - 48}{3}\]
