Solution for 4x^2+34x+16=0 equation:



4x^2+34x+16=0
a = 4; b = 34; c = +16;
Δ = b2-4ac
Δ = 342-4·4·16
Δ = 900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{900}=30$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(34)-30}{2*4}=\frac{-64}{8} =-8 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(34)+30}{2*4}=\frac{-4}{8} =-1/2 $
