(4x+2)(10x-1)=10
We move all terms to the left:
(4x+2)(10x-1)-(10)=0
We multiply parentheses ..
(+40x^2-4x+20x-2)-10=0
We get rid of parentheses
40x^2-4x+20x-2-10=0
We add all the numbers together, and all the variables
40x^2+16x-12=0
a = 40; b = 16; c = -12;
Δ = b2-4ac
Δ = 162-4·40·(-12)
Δ = 2176
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{2176}=\sqrt{64*34}=\sqrt{64}*\sqrt{34}=8\sqrt{34}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(16)-8\sqrt{34}}{2*40}=\frac{-16-8\sqrt{34}}{80} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(16)+8\sqrt{34}}{2*40}=\frac{-16+8\sqrt{34}}{80} $
