2x(4x-5)=14
We move all terms to the left:
2x(4x-5)-(14)=0
We multiply parentheses
8x^2-10x-14=0
a = 8; b = -10; c = -14;
Δ = b2-4ac
Δ = -102-4·8·(-14)
Δ = 548
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{548}=\sqrt{4*137}=\sqrt{4}*\sqrt{137}=2\sqrt{137}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-10)-2\sqrt{137}}{2*8}=\frac{10-2\sqrt{137}}{16} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-10)+2\sqrt{137}}{2*8}=\frac{10+2\sqrt{137}}{16} $
