Solution for 49x2+6x-2=0 equation:



49x^2+6x-2=0
a = 49; b = 6; c = -2;
Δ = b2-4ac
Δ = 62-4·49·(-2)
Δ = 428
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:
$\sqrt{\Delta}=\sqrt{428}=\sqrt{4*107}=\sqrt{4}*\sqrt{107}=2\sqrt{107}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-2\sqrt{107}}{2*49}=\frac{-6-2\sqrt{107}}{98} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+2\sqrt{107}}{2*49}=\frac{-6+2\sqrt{107}}{98} $
