1.4x12 / 4x
2.d+7 / d^249
3.t^225 / t^2+t20
4.2x^2+6x+4 / 4x^212x16
5.6y / y^22y24
1. 12 [4x] cancels out. so you're left with just 12.
2. 1/d7 factor the d^249 to (d+7)(d7). cancel out the (d+7)
3. (t5)/(t4) factor both numerator and denominator. so then it's: (t5)(t+5)/(t+5)(t4) cancel out the (t+5)'s
4. (x+2)/(2x8) factor out a 2 from the numerator and factor out a 4 from the denominator. [2(x^2+3x+2)]/[4(x^23x4)] then factor the polynomial expressions. so then you should have [2(x+2)(x+1)]/[4(x4)(x+1)]. cancel out the (x+1). reduce the coefficients 2 and 4. then redistribute the 2 in the denominator.
5. 1/(y+4) factor out a 1 from the numerator. factor the denominator. you should have [(y6)/(y6)(y+4)] cancel out the (y6).

Explain why this statement is true: when simplifying rational expressions, we must cancel factors only, and not terms. Give an example using just numbers.
