v=6 or v=1

Explanation:

rearrange and equate to zero

7v2+35v42=0standard form

take out a common factor of 7

7(v2+5v6)=0

the factors of - 6 which sum to + 5 are + 6 and - 1

7(v+6)(v1)=0

equate each factor to zero and solve for v

v+6=0v=6

v1=0v=1

the solutions are v=6 or v=1

v=1or6

Explanation:

7v242=35v

7v2+35v42=0

7(v2+56)=0

v2+56=0

(v+6)(v1)=0

Using the 0 product property (if ab=0, then a=0orb=0)

v+6=0
v=6

v1=0
v=1
