2x^2+3x is the expression which is equivalent to $x\left(2x+3\right)$ .

In other words:

$x\left(2x+3\right)=2x^2+3x$

Step-by-step explanation:

Given the expression

$x\left(2x+3\right)$

solving

$x\left(2x+3\right)$

$\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac$

$a=x,\:b=2x,\:c=3$

$=x\cdot \:2x+x\cdot \:3$

=2xx+3x

=2x^2+3x ∴ 2xx=2x^2

Thus,

$x\left(2x+3\right)=2x^2+3x$

Therefore, 2x^2+3x is the expression which is equivalent to $x\left(2x+3\right)$ .
