I think they are radicals anyway >_> heres some probs from my HW that i didnt get.
Hopefully those will format correctly..Code:11. *figured it out* 31. *figured out* 41. Find LCD 9 3 --- and --- 8x 2x+4 answer: 8x(x+2) 59. 9 (blank) --- = ----- x+3 2(x+3) and 63. x (blank) ----- = ----- x^2+6x+8 (X+4)(X+2)(X+1)
anyway.
My book does a horrible job of showing how to do these.. -__-.. and purple math doesnt help me much either.
Thanks so much

59.
9/(x+3) = 9/(x+3) * (2/2) = 2*9/2(x+3) = 18/2(x+3)
so the blank is 18
notice that we had a fraction where the denominator increased by a factor of 2. to maintain equality, that is, to keep the fraction at the same value it was before, the numerator also had to increase by factor of 2
