Heya..,
Your answer is here..,
x2 - 5x + 6=0
- by completing square method.
(1/2×x)^2
= (1/2 × 5)^2
=( 1/4 × 25)
= 25/4
add 25/4 in equation
x^2 - 5x + 25/4 = -6×4/1×4 + 25/4
=( ×-5/2)^2 = -24/4 + 25/4
=( x - 5/2)^2 = +-root of 1/4
x - 5/2 = +-1/2.
= x = -1/2 + 5/2 or x = 1/2 + 5/2
= x = 4/2. x = 6/2
= x = 2. x = 3.
hope its will helpful to you...
