Question

how do you factor: 4v²-33v+8?

Answer 1

(v-8) (4 v-1)

Answer 2

(4v-1)(v-8)

Answer 3

wow!

Answer 4

how do you get that though?

Answer 5

4x8=32. So you need two numbers that multiply to 32 and add up to -33. Those two are -32 and -1.

Answer 8

Then plug them in.... and you get...
4v^2-32v-v+8...
Take common...
4v(v-8)-1(v-8)
then you get...
(4v-1)(v-8)

Answer 9

Answer is (v-8)(4v-1)
See the attached image for how I got that answer.

Answer 10

ok... so now I have 4v²+15-4. 4X4 is 16...and I'm not seeing a way to factor that out.
