$= 2 x^{2} + 7 x + 3$ $= 2x^2 +7x +3$

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

$= 2 x \times (x) + 2 x \times (3) + 1 \times (x) + 1 \times (3)$ $= color(blue)(2x xx (x ) + 2x xx (3)) + color(green)(1 xx (x) + 1 xx (3)$

$= 2 x^{2} + 6 x + 1 x + 3$ $= 2x^2 +6x + 1x +3$

$= 2 x^{2} + 7 x + 3$ $= 2x^2 +7x +3$

How do you multiply (2x+1)(x+3)(2x+1)(x+3) (2x+1)(x+3)?
