Solving A Quadratic Equation By FactoringSince, 3x2 – 5x + 2 is a quadratic polynomial; 3x2 – 5x + 2 = 0 is a quadratic equation. Also, 3x2 – 5x + 2 = 3x2 – 3x – 2x + 2 [Factorising] = 3x (x – 1) – 2(x – 1) = (x – 1) (3x – 2) In the same way : 3x2 – 5x + 2 = 0 ⇒ 3x2 – 3x – 2x + 2 = 0 [Factorising L.H.S.] ⇒ (x – 1) (3x – 2) = 0 i.e., x – 1 = 0 or … [Read more...] about Solving A Quadratic Equation By Factoring
