x 2 − 6 x + 6 = 0 a = 1 , b = − 6 , c = 6 Δ = b 2 − 4 a c = ( − 6 ) 2 − 4 ⋅ 1 ⋅ 6 = 36 − 24 = 12 Δ = 12 = 4 ⋅ 3 = 2 3 x 1 = 2 a − b − Δ = 2 6 − 2 3 = 2 2 ( 3 − 3 ) = 3 − 3 x 2 = 2 a − b + Δ = 2 6 + 2 3 = 2 2 ( 3 + 3 ) = 3 + 3
x 2 − 6 x + 6 = 0 x 2 − 6 x + 9 − 3 = 0 ( x − 3 ) 2 = 3 x − 3 = 3 ∨ x − 3 = − 3 x = 3 + 3 ∨ x = 3 − 3
To solve the equation x 2 − 6 x + 6 = 0 , we use the quadratic formula: x = 2 a − b ± b 2 − 4 a c . We find the solutions to be x 1 = 3 − 3 and x 2 = 3 + 3 .
