X2-3x-10 . X2+8x
X2+2x X2+3x-40

all X2's are x squared can someone help me with this ? I'm new at this.
 
factor each numerator and denominator ...

\(\displaystyle \L \frac{(x-5)(x+2)}{x(x+2)} \cdot \frac{x(x+8)}{(x+8)(x-5)}\)

now ... something really easy ... cancel the common factors in the numerator and denominator. what do you get?
