Question

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

Answer 1

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 = $\frac{1}{2}$

Answer 2

Answer:

Hey!! Ur answer:

$2x^{2} +7x+3\\ =2x^{2} +6x+x+3\\ =2x(x+3)+1(x+3)\\ =(2x+1)(x+3)$
