(15x+29)(26x-4)=90
We move all terms to the left:
(15x+29)(26x-4)-(90)=0
We multiply parentheses ..
(+390x^2-60x+754x-116)-90=0
We get rid of parentheses
390x^2-60x+754x-116-90=0
We add all the numbers together, and all the variables
390x^2+694x-206=0
a = 390; b = 694; c = -206;
Δ = b2-4ac
Δ = 6942-4·390·(-206)
Δ = 802996
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{802996}=\sqrt{4*200749}=\sqrt{4}*\sqrt{200749}=2\sqrt{200749}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(694)-2\sqrt{200749}}{2*390}=\frac{-694-2\sqrt{200749}}{780} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(694)+2\sqrt{200749}}{2*390}=\frac{-694+2\sqrt{200749}}{780} $
