(3x+10)(5x+16)=180
We move all terms to the left:
(3x+10)(5x+16)-(180)=0
We multiply parentheses ..
(+15x^2+48x+50x+160)-180=0
We get rid of parentheses
15x^2+48x+50x+160-180=0
We add all the numbers together, and all the variables
15x^2+98x-20=0
a = 15; b = 98; c = -20;
Δ = b2-4ac
Δ = 982-4·15·(-20)
Δ = 10804
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{10804}=\sqrt{4*2701}=\sqrt{4}*\sqrt{2701}=2\sqrt{2701}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(98)-2\sqrt{2701}}{2*15}=\frac{-98-2\sqrt{2701}}{30} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(98)+2\sqrt{2701}}{2*15}=\frac{-98+2\sqrt{2701}}{30} $
