Reduce each rational expression to lowest terms. Assume that the variables represent only numbers for which the denominators are nonzero 6.1 34, 78,88
a^2-b^2
a-b = (a-b)(a+b) / (a-b) = a+b
Reduce to lowest terms
4x^2
2x^9
= 2 x^2 / x^9 = 2/x^7
-2x-8
x^2+2x-8 we will factor both top and bottom and get:
= -2(x+4) / (x+4)(x-2) = -2 / x-2 , after simplifying by x+4.
perform indicted operation 6.2 22,68,74
3 * 2a+2
a^2+a 6
= 3*2(a+1) / a(a+1)*6 = 1/a , after simplifying by 6 and a+1
-2a^2 *20a
3a^2 15a^3
= -40 a^3 / 45 a^5 = -8/9a^2 , after simplifying by 5 and a^3
w^2-1 * w-1
(w-1)^2 w^2+2w+1
= ...
