1) (x+4)(x+2) / (x-4)(x+4) = x=2 / x-4; x not = 4 since the den. = 0
2) x=3 / x+4; x not = -4 since den. =0

the reason being x^0 = a million (some thing to the ability 0 is a million) simplest thanks to attempt this branch is to subtract the exponent values interior the denominator from the fee interior the numerator for an identical base. We get x^(5-2)y^(3-3)z^(2-7) = x^3y^0z^-5 that is an identical as x^3/y^5
