(x-5)x=176

Solution for (x-5)x=176 equation:

(x-5)x=176

We move all terms to the left:

(x-5)x-(176)=0

We multiply parentheses

x^2-5x-176=0

a = 1; b = -5; c = -176;
Δ = b2-4ac
Δ = -52-4·1·(-176)
Δ = 729
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{729}=27$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-5)-27}{2*1}=\frac{-22}{2}
=-11
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+27}{2*1}=\frac{32}{2}
=16
