Solution for 9x2+2x-43=0 equation:



9x^2+2x-43=0
a = 9; b = 2; c = -43;
Δ = b2-4ac
Δ = 22-4·9·(-43)
Δ = 1552
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:
$\sqrt{\Delta}=\sqrt{1552}=\sqrt{16*97}=\sqrt{16}*\sqrt{97}=4\sqrt{97}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-4\sqrt{97}}{2*9}=\frac{-2-4\sqrt{97}}{18} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+4\sqrt{97}}{2*9}=\frac{-2+4\sqrt{97}}{18} $
