Question

factorise 2x square + 7 x + 3

Answer 1

hey mate 
your answer is here

=2x square+7x+3
=2xsquare+(x+6x)+3
=(2xsquare+x)(6x+3)
=x(2x+1)+3(2x+1)
= (x+3)(2x+1)

plz make me brainliest

Answer 2

Answer:

x=3,-0.5

Step-by-step explanation:

Given : $2x^2+7x+3$

To Find: x

Solution:

$2x^2+7x+3$

We will use discriminant rule  : $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

a = 2

b = 7

c= 3

Substitute the values .

$x=\frac{-7\pm\sqrt{7^2-4(2)(3)}}{2(2)}$

$x=\frac{-7+\sqrt{7^2-4(2)(3)}}{2(2)},\frac{-7-\sqrt{7^2-4(2)(3)}}{2(2)}$

$x=3,-0.5$
