X2-34x+64=0

Solution for X2-34x+64=0 equation:

X2-34X+64=0

We add all the numbers together, and all the variables

X^2-34X+64=0

a = 1; b = -34; c = +64;
Δ = b2-4ac
Δ = -342-4·1·64
Δ = 900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{900}=30$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-34)-30}{2*1}=\frac{4}{2}
=2
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-34)+30}{2*1}=\frac{64}{2}
=32
