Question

how do I factor 4v²+15v-4?

Answer 1

did u tried to solve?

Answer 2

4(-4)=-16.
Two numbers that add up to 15 and multiply to -16 are....16 and -1.
Plug them in.

Answer 3

(4x-1)(x+4)

Answer 4

yes I can't think of anything that could be 4x4 and also equal to 15..

Answer 5

4v^2+16v-v-4
Take common...
4v(v+4)-1(v+4)=
(4v-1)(v+4)

Answer 6

RIght.

Answer 7

thats v instead of x ----- (4v-1)(v+4) hehehe

Answer 8

4v^2+16v-v-4
Take common...
4v(v+4)-1(v+4)=
\[\huge (4v-1)(v+4)\]

Answer 9

tell me if this is wrong=
8v²+31v-4
(8v²-1v)(32v-4)
1v(8v-1) 4(8v-1)
(v+4)(8v-1)

Answer 10

\[4v^2+15v-4\]
\[4v^2+16v-y-4\]
\[4v(v+4)-1(v+4)\]
\[(4v-1)(v+4)\]

Answer 11

\[8v^2+31v-4\]
\[8v^2+32v-1v-4\]
\[8v(v+4)-1(v+4)\]
\[(8v-1)((v+4)\]
ur answer and this answer is same and ur process is also right hence u r right
