6.1 pg. 381 ex.4 Reducing

Reducing:

a) 30/42 15/21
2/30
2/42
3/15=5
3/21=7
the problem has been factored out to the gcf;
the 2's and the 3's have been cancelled out
30/42 reduced to lowest terms=5/7.

b) x2-9/6x+18

factor and reduce by the same number find the gcf and cancel out like terms.

(x-3)(x+3)/6(X+3) factor out the x+3'S x-3/6

x2-9/6x+18 is reduced to lowest terms=x-3/6.

c) 3x2+9x+6/2x2-8

3(x+2)(x+1) look into the answer.
