x=12;2(x+60)8x

Solution for x=12;2(x+60)8x equation:

x=122(x+60)8x

We move all terms to the left:

x-(122(x+60)8x)=0


We calculate terms in parentheses: -(122(x+60)8x), so:

122(x+60)8x

We multiply parentheses

976x^2+58560x

Back to the equation:

-(976x^2+58560x)


We get rid of parentheses

-976x^2+x-58560x=0

We add all the numbers together, and all the variables

-976x^2-58559x=0

a = -976; b = -58559; c = 0;
Δ = b2-4ac
Δ = -585592-4·(-976)·0
Δ = 3429156481
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{3429156481}=58559$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-58559)-58559}{2*-976}=\frac{0}{-1952}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-58559)+58559}{2*-976}=\frac{117118}{-1952}
=-59+975/976
