x^2-2x+(13/4)=0
We add all the numbers together, and all the variables
x^2-2x+(+13/4)=0
We get rid of parentheses
x^2-2x+13/4=0
We multiply all the terms by the denominator
x^2*4-2x*4+13=0
Wy multiply elements
4x^2-8x+13=0
a = 4; b = -8; c = +13;
Δ = b2-4ac
Δ = -82-4·4·13
Δ = -144
Delta is less than zero, so there is no solution for the equation
