(8+5x)(7+3x)=0
We add all the numbers together, and all the variables
(5x+8)(3x+7)=0
We multiply parentheses ..
(+15x^2+35x+24x+56)=0
We get rid of parentheses
15x^2+35x+24x+56=0
We add all the numbers together, and all the variables
15x^2+59x+56=0
a = 15; b = 59; c = +56;
Δ = b2-4ac
Δ = 592-4·15·56
Δ = 121
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{121}=11$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(59)-11}{2*15}=\frac{-70}{30} =-2+1/3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(59)+11}{2*15}=\frac{-48}{30} =-1+3/5 $
