16y^2-66y+9=0
a = 16; b = -66; c = +9;
Δ = b2-4ac
Δ = -662-4·16·9
Δ = 3780
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{3780}=\sqrt{36*105}=\sqrt{36}*\sqrt{105}=6\sqrt{105}$$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-66)-6\sqrt{105}}{2*16}=\frac{66-6\sqrt{105}}{32} $$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-66)+6\sqrt{105}}{2*16}=\frac{66+6\sqrt{105}}{32} $
