(3x+1)(x+9)=180
We move all terms to the left:
(3x+1)(x+9)-(180)=0
We multiply parentheses ..
(+3x^2+27x+x+9)-180=0
We get rid of parentheses
3x^2+27x+x+9-180=0
We add all the numbers together, and all the variables
3x^2+28x-171=0
a = 3; b = 28; c = -171;
Δ = b2-4ac
Δ = 282-4·3·(-171)
Δ = 2836
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{2836}=\sqrt{4*709}=\sqrt{4}*\sqrt{709}=2\sqrt{709}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(28)-2\sqrt{709}}{2*3}=\frac{-28-2\sqrt{709}}{6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(28)+2\sqrt{709}}{2*3}=\frac{-28+2\sqrt{709}}{6} $
