we have
f(x)= x^2 - 10x - 24
g(x) = 2x - 24
we know that
(f/g)x =f(x)/g(x)
so
substitute
(f/g)x =(x^2 - 10x - 24)/(2x-24)
simplify the expression
we have that
2x-24=2(x-12)
and
x^2 - 10x - 24=(x-12)(x+2)
substitute in the original expression
(f/g)x=(x-12)(x+2)/{2(x-12)}
simplify
(f/g)x=(x+2)/2
2x-24=2x-12(2)
step 1
Factor 2
2x-12(2)=2(x-12)
