-5v^2+47=-7v^2+10+14v
We move all terms to the left:
-5v^2+47-(-7v^2+10+14v)=0
We get rid of parentheses
-5v^2+7v^2-14v-10+47=0
We add all the numbers together, and all the variables
2v^2-14v+37=0
a = 2; b = -14; c = +37;
Δ = b2-4ac
Δ = -142-4·2·37
Δ = -100
Delta is less than zero, so there is no solution for the equation
