(3x+4)(5x+1)=0
We multiply parentheses ..
(+15x^2+3x+20x+4)=0
We get rid of parentheses
15x^2+3x+20x+4=0
We add all the numbers together, and all the variables
15x^2+23x+4=0
a = 15; b = 23; c = +4;
Δ = b2-4ac
Δ = 232-4·15·4
Δ = 289
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{289}=17$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(23)-17}{2*15}=\frac{-40}{30} =-1+1/3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(23)+17}{2*15}=\frac{-6}{30} =-1/5 $
