3-1x(5-x)=3-4x

Solution for 3-1x(5-x)=3-4x equation:

3-1x(5-x)=3-4x

We move all terms to the left:

3-1x(5-x)-(3-4x)=0

We add all the numbers together, and all the variables

-1x(-1x+5)-(-4x+3)+3=0

We multiply parentheses

1x^2-5x-(-4x+3)+3=0

We get rid of parentheses

1x^2-5x+4x-3+3=0

We add all the numbers together, and all the variables

x^2-1x=0

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