Solution for 3x^2+4x=243 equation:



3x^2+4x=243
We move all terms to the left:
3x^2+4x-(243)=0
a = 3; b = 4; c = -243;
Δ = b2-4ac
Δ = 42-4·3·(-243)
Δ = 2932
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:
$\sqrt{\Delta}=\sqrt{2932}=\sqrt{4*733}=\sqrt{4}*\sqrt{733}=2\sqrt{733}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-2\sqrt{733}}{2*3}=\frac{-4-2\sqrt{733}}{6} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+2\sqrt{733}}{2*3}=\frac{-4+2\sqrt{733}}{6} $
