Question

i just wnat to see if i got this question right.
factor the trinomial.
5d^2-8d-8
i got 5(d^2+4d) -2(d+4)
is it right?

Answer 1

no, the expression you got is not a factorization.

Answer 2

nope. the breaking up will be difficult. you need to use the quadratic formulae.

Answer 3

so how owuld i correct it?

Answer 4

this is not factorable.

Answer 5

im sorry the 8d is a 18d

Answer 6

yeah you are right then. '__'

Answer 7

okay thannks

Answer 8

in that case, now it is factorable with the -18d

Answer 9

5d^2 - 18d - 8 = (5d +2)(d - 4)

Answer 10

yea thats correct

Answer 11

okay thanks
