-9v(4v+2)+5v=3v+50
We move all terms to the left:
-9v(4v+2)+5v-(3v+50)=0
We add all the numbers together, and all the variables
5v-9v(4v+2)-(3v+50)=0
We multiply parentheses
-36v^2+5v-18v-(3v+50)=0
We get rid of parentheses
-36v^2+5v-18v-3v-50=0
We add all the numbers together, and all the variables
-36v^2-16v-50=0
a = -36; b = -16; c = -50;
Δ = b2-4ac
Δ = -162-4·(-36)·(-50)
Δ = -6944
Delta is less than zero, so there is no solution for the equation
