Factorise the following 2x^2+7x+3 by sum and product​

Answer»

ANSWER:

X = 3                    OR        x = \frac{1}{2}

Step-by-step EXPLANATION:

The EQUATION : 2x^{2} - 7x + 3

SUM : -7

Product : 6

It can be split as -1 and -6.

  2x^{2} - x - 6x + 3 = 0

x(2x - 1) - 3(2x - 1) = 0

(2x - 1)(x - 3) = 0

∴ x - 3 = 0             OR        2x - 1 = 0

  x = 3                   OR        2x = 1

∴x = 3                   OR        x = \frac{1}{2}
