(x-6)(x-4)=24

Solution for (x-6)(x-4)=24 equation:

(x-6)(x-4)=24

We move all terms to the left:

(x-6)(x-4)-(24)=0

We multiply parentheses ..

(+x^2-4x-6x+24)-24=0

We get rid of parentheses

x^2-4x-6x+24-24=0

We add all the numbers together, and all the variables

x^2-10x=0

a = 1; b = -10; c = 0;
Δ = b2-4ac
Δ = -102-4·1·0
Δ = 100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{100}=10$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-10)-10}{2*1}=\frac{0}{2}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-10)+10}{2*1}=\frac{20}{2}
=10
