We'll apply the quadratic
formula
The original equation is:
x^2-5x+6=0
x1 = [-b + sqrt(b^2 -
4ac)]/2a
We'll identify the
coefficients:
a = 1
b =
-5
c = 6
b^2 - 4ac = (-5)^2 -
4*1*6 = 25 - 24
sqrt(b^2 - 4ac) = sqrt(25 -
24)
sqrt(b^2 - 4ac) = 1
We'll
substitute in the formula:
x1 = [-(-5) + sqrt(25 -
24)]/2
x1 = (5+1)/2
x1 =
3
x2 = (5-1)/2
x2 =
2
The roots of the equation are {2 ;
3}.
