4x*4x-9x-5=0
We add all the numbers together, and all the variables
-9x+4x*4x-5=0
Wy multiply elements
16x^2-9x-5=0
a = 16; b = -9; c = -5;
Δ = b2-4ac
Δ = -92-4·16·(-5)
Δ = 401
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{-(-9)-\sqrt{401}}{2*16}=\frac{9-\sqrt{401}}{32} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-9)+\sqrt{401}}{2*16}=\frac{9+\sqrt{401}}{32} $
