Question

Factor the polynomial completely: 2 p 2 − 15 p − 8

Answer 1

you do the ac method

Answer 2

2*8 = 16 right ?

Answer 3

the first is 2p squared

Answer 4

yes

Answer 5

now find the factors of 16 that combines to b which is -15

Answer 6

now find the factors of 16 that combines to b which is -15

Answer 7

so 1*-16 is 16 and 1-16 is -15

Answer 8

so you can write the eqn as\[2p^2 + p -16p -8\]

Answer 9

now you do factoring by grouping

Answer 10

okay thank you!

Answer 11

as so\[p(2p+1) -8(2p+1)\]

\[(p-8)(2p+1)\]

Answer 12
