5x(139-x)+10x=1035
We move all terms to the left:
5x(139-x)+10x-(1035)=0
We add all the numbers together, and all the variables
5x(-1x+139)+10x-1035=0
We add all the numbers together, and all the variables
10x+5x(-1x+139)-1035=0
We multiply parentheses
-5x^2+10x+695x-1035=0
We add all the numbers together, and all the variables
-5x^2+705x-1035=0
a = -5; b = 705; c = -1035;
Δ = b2-4ac
Δ = 7052-4·(-5)·(-1035)
Δ = 476325
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{476325}=\sqrt{225*2117}=\sqrt{225}*\sqrt{2117}=15\sqrt{2117}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(705)-15\sqrt{2117}}{2*-5}=\frac{-705-15\sqrt{2117}}{-10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(705)+15\sqrt{2117}}{2*-5}=\frac{-705+15\sqrt{2117}}{-10} $
