In a three dimensional space the equation x2 – 5x + 6 = 0 represents
Given: x2 – 5x + 6 = 0
x2 – 5x + 6 = 0
⇒ x2 – 3x – 2x + 6 = 0
⇒ x(x – 3) – 2(x – 3) = 0
⇒ (x – 3)(x – 2) = 0
⇒ (x – 3) = 0 or (x – 2) = 0
⇒ x = 3 or x = 2
Both the results represents planes which are parallel to yz-plane
Hence, x2 – 5x + 6 = 0 represents planes
