**Simplifying Rational Expressions**

1.4x12 / 4x 2.d+7 / d^2-49 3.t^2-25 / t^2+t-20 4.2x^2+6x+4 / 4x^2-12x-16 5.6-y / y^2-2y-24 1. 12 [4x] cancels out. so you're left with just 12. 2. 1/d-7 factor the d^2-49 to (d+7)(d-7). cancel out the (d+7) 3. (t-5)/(t-4) factor both numerator and denominator. so then it's: (t...
