X2-9X-432=0
We add all the numbers together, and all the variables
X^2-9X-432=0
a = 1; b = -9; c = -432;
Δ = b2-4ac
Δ = -92-4·1·(-432)
Δ = 1809
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}$$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{1809}=\sqrt{9*201}=\sqrt{9}*\sqrt{201}=3\sqrt{201}$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-9)-3\sqrt{201}}{2*1}=\frac{9-3\sqrt{201}}{2} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-9)+3\sqrt{201}}{2*1}=\frac{9+3\sqrt{201}}{2} $
