16.5^2+x^2=18.7^2
We move all terms to the left:
16.5^2+x^2-(18.7^2)=0
We add all the numbers together, and all the variables
x^2-77.44=0
a = 1; b = 0; c = -77.44;
Δ = b2-4ac
Δ = 02-4·1·(-77.44)
Δ = 309.76
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{309.76}}{2*1}=\frac{0-\sqrt{309.76}}{2} =-\frac{\sqrt{}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{309.76}}{2*1}=\frac{0+\sqrt{309.76}}{2} =\frac{\sqrt{}}{2} $
