question\nexpress as a trinomial.\n(3x - 8)(2x + 10)\nanswer attempt 1 out of 2

Explanation:

Step1: Use FOIL method

$(3x - 8)(2x+10)=3x\times2x+3x\times10-8\times2x - 8\times10$

Step2: Calculate each product

$3x\times2x = 6x^{2}$, $3x\times10=30x$, $-8\times2x=-16x$, $-8\times10 = - 80$

Step3: Combine like - terms

$6x^{2}+30x-16x - 80=6x^{2}+(30x-16x)-80=6x^{2}+14x - 80$

Answer:

$6x^{2}+14x - 80$
