use the chart to multiply the binomial by the trinomial. which polynomial is the correct product? (2y + 3)(3y² + 4y + 5) 15y³ + 17y² + 22y + 15 6y³ + 17y² + 22y + 15 6y³ + 20y² + 22y + 15 6y³ + 17y² + 22y + 25
Answer
Explanation:
Step1: Multiply each term of binomial by trinomial
$(2y + 3)(3y^{2}+4y + 5)=2y(3y^{2}+4y + 5)+3(3y^{2}+4y + 5)$
Step2: Distribute $2y$
$2y(3y^{2}+4y + 5)=2y\times3y^{2}+2y\times4y+2y\times5 = 6y^{3}+8y^{2}+10y$
Step3: Distribute $3$
$3(3y^{2}+4y + 5)=3\times3y^{2}+3\times4y+3\times5=9y^{2}+12y + 15$
Step4: Combine like - terms
$(6y^{3}+8y^{2}+10y)+(9y^{2}+12y + 15)=6y^{3}+(8y^{2}+9y^{2})+(10y + 12y)+15=6y^{3}+17y^{2}+22y + 15$
Answer:
$6y^{3}+17y^{2}+22y + 15$
