(5+v)(4v+7)=0
We add all the numbers together, and all the variables
(v+5)(4v+7)=0
We multiply parentheses ..
(+4v^2+7v+20v+35)=0
We get rid of parentheses
4v^2+7v+20v+35=0
We add all the numbers together, and all the variables
4v^2+27v+35=0
a = 4; b = 27; c = +35;
Δ = b2-4ac
Δ = 272-4·4·35
Δ = 169
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{169}=13$$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(27)-13}{2*4}=\frac{-40}{8} =-5 $$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(27)+13}{2*4}=\frac{-14}{8} =-1+3/4 $
