x2-48x-225=0
We add all the numbers together, and all the variables
x^2-48x-225=0
a = 1; b = -48; c = -225;
Δ = b2-4ac
Δ = -482-4·1·(-225)
Δ = 3204
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{3204}=\sqrt{36*89}=\sqrt{36}*\sqrt{89}=6\sqrt{89}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-48)-6\sqrt{89}}{2*1}=\frac{48-6\sqrt{89}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-48)+6\sqrt{89}}{2*1}=\frac{48+6\sqrt{89}}{2} $
