Factorize:- 2x^2-x+3

Answer»

$answer = >$

Common factor -

$\: 2x ^ 2 - x + 3 - 1(2x ^ 2 + x - 3)$

USE the sum-product PATTERN

$\: - 1(2x ^ 2 + x - 3)$

$\: - 1(2x ^ 2 + 3x - 2x - 3)$

Common factor from the TWO pairs -

$- 1(2x {}^{2} + 3x - 2x + 3) \\ - 1(x(2x + 3) - 1(2x + 3)$

Rewrite in FACTORED form -

$- 1(x - 1)(2x + 3)) \\ - 1(x - 1)(2x + 3)$
