Q23 of 83 Page 90

…………… is a solution of quadratic equation x2 — 3x + 2 = 0

x2 — 3x + 2 = 0

⇒ x2 —(2 + 1)x + 2 = 0


⇒ x2 — 2x – x + 2 = 0


⇒ x(x – 2) – 1(x – 2) = 0


⇒ (x – 1) = 0 or (x – 2) = 0


⇒ x = 1 or x = 2


(B) doesn’t match the solution.


(C) doesn’t match the solution.


(D) doesn’t match the solution.
