x^2+17x+14=3x

Solution for x^2+17x+14=3x equation:

x^2+17x+14=3x

We move all terms to the left:

x^2+17x+14-(3x)=0

We add all the numbers together, and all the variables

x^2+14x+14=0

a = 1; b = 14; c = +14;
Δ = b2-4ac
Δ = 142-4·1·14
Δ = 140
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:

$\sqrt{\Delta}=\sqrt{140}=\sqrt{4*35}=\sqrt{4}*\sqrt{35}=2\sqrt{35}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(14)-2\sqrt{35}}{2*1}=\frac{-14-2\sqrt{35}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(14)+2\sqrt{35}}{2*1}=\frac{-14+2\sqrt{35}}{2}
