using the distributive property, marta multiplied the binomial (2x + 3) by the trinomial (x² + x - 2) and got the expression below. (2x)(x²)+(2x)(x)+(2x)(-2)+(3)(x²)+(3)(x)+(3)(-2) which is the simplified product? 2x³ + 6x² - x - 6 2x³ + x² - x - 6 2x³ + 5x² - x - 6 2x³ - x² - 7x - 6

Answer

Explanation:

Step1: Expand each term

$(2x)(x^{2})=2x^{3}$, $(2x)(x) = 2x^{2}$, $(2x)(- 2)=-4x$, $(3)(x^{2})=3x^{2}$, $(3)(x)=3x$, $(3)(-2)=-6$.

Step2: Combine like - terms

$2x^{3}+2x^{2}-4x + 3x^{2}+3x-6=2x^{3}+(2x^{2}+3x^{2})+(-4x + 3x)-6$. $2x^{3}+5x^{2}-x - 6$.

Answer:

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