x=4x(0.25x)

Solution for x=4x(0.25x) equation:

x=4x(0.25x)

We move all terms to the left:

x-(4x(0.25x))=0

We add all the numbers together, and all the variables

x-(4x(+0.25x))=0


We calculate terms in parentheses: -(4x(+0.25x)), so:

4x(+0.25x)

We multiply parentheses

0x^2

We add all the numbers together, and all the variables

x^2

Back to the equation:

a = -1; b = 1; c = 0;
Δ = b2-4ac
Δ = 12-4·(-1)·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

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