Answer 1

(x - 7)(x + 2 ) 2x(x-4)

------------------------- * -------------------------------

( x - 4 )(x + 2 ) ( x + 7)( x + 3 )

x+2 cancels

x-4 cancels

2x(x-5)

-------

(x+7)(x+3)

Answer 2

You need to factor these and change the division to multiplication.

(x-7)(x+2) x 2x(x-4)

(x-4)(x+2) (x+3)(x+7)

Next, see what cancels out, (x+2) and (x-4) What remains is the solution

2x(x-7)

(x+3)(x+7)
