which equals the product of (x - 3)(2x + 1)?\n2x² - 7x - 3\n2x² - 5x - 3\n3x - 2\n6x²

Explanation:

Step1: Aplicar la regla FOIL

$(x - 3)(2x+1)=x\times2x+x\times1+(-3)\times2x+(-3)\times1$

Step2: Simplificar cada término

$x\times2x = 2x^{2}$, $x\times1=x$, $(-3)\times2x=-6x$, $(-3)\times1 = - 3$

Step3: Combinar términos semejantes

$2x^{2}+x-6x - 3=2x^{2}-5x - 3$

Answer:

$2x^{2}-5x - 3$
