4. Multiply. give your answer in standard form. (2n^2 - 7n + 2)(3n + 1) (1 point) 6n^3 - 23n62 - n +2 6n^3 - 19n^2 - n + 2 6n^3 - 19n^2 - 13n + 2 6n^3 + 23n^2 + 13n + 2

jagr2713 (jagr2713):

what do you think it is

OpenStudy (anonymous):

i have no idea @jagr2713

jagr2713 (jagr2713):

so 6n^3

jagr2713 (jagr2713):

7*3=21 21-2=19

jagr2713 (jagr2713):

6n^3-19n^2

jagr2713 (jagr2713):

(x+5) and (x-3) (x+5) and (x+3) (x-5) and (x-3) (x+5)and (x+3)

jagr2713 (jagr2713):

x^2+2x=3x 15/3=5 so its (x+5) right

jagr2713 (jagr2713):

so what can you eliminate

OpenStudy (anonymous):
