We add all the numbers together, and all the variables

x+x+(+1/2)*x+(+1/4)*x+1-100=0

We add all the numbers together, and all the variables

2x+(+1/2)*x+(+1/4)*x-99=0

We multiply parentheses

x^2+x^2+2x-99=0

We add all the numbers together, and all the variables

2x^2+2x-99=0

a = 2; b = 2; c = -99;
Δ = b2-4ac
Δ = 22-4·2·(-99)
Δ = 796
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{796}=\sqrt{4*199}=\sqrt{4}*\sqrt{199}=2\sqrt{199}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2\sqrt{199}}{2*2}=\frac{-2-2\sqrt{199}}{4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2\sqrt{199}}{2*2}=\frac{-2+2\sqrt{199}}{4}
