Answer 1

factorize the denominator and numerator

Answer 2

then cancel out the common terms

Answer 3

how do i factorize the denominator and numerator?

Answer 4

d^2 - 9 = (d+3)(d-3)

Answer 5

and 2d^2 + 14d + 24 = 2(d+4)(d+3)

Answer 6

now d+3 is common to both so it cancels out...so it comes to 2(d+4)/(d-3)

Answer 7

can you help me with a couple more?

Answer 8

go on...try the others on ur own lyk i told u 2
