(x+5)(x+3)=(5x+1)x
We move all terms to the left:
(x+5)(x+3)-((5x+1)x)=0
We multiply parentheses ..
(+x^2+3x+5x+15)-((5x+1)x)=0
We calculate terms in parentheses: -((5x+1)x), so:We get rid of parentheses
(5x+1)x
We multiply parentheses
5x^2+x
Back to the equation:
-(5x^2+x)
x^2-5x^2+3x+5x-x+15=0
We add all the numbers together, and all the variables
-4x^2+7x+15=0
a = -4; b = 7; c = +15;
Δ = b2-4ac
Δ = 72-4·(-4)·15
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$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(7)-17}{2*-4}=\frac{-24}{-8} =+3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+17}{2*-4}=\frac{10}{-8} =-1+1/4 $
