Question

question
express as a trinomial.
(2x + 6)(x - 5)
answer
attempt 1 out of 2

Explanation:

Step1: Use FOIL method

$(2x + 6)(x - 5)=2x\times x+2x\times(- 5)+6\times x+6\times(-5)$

Step2: Simplify each term

$2x\times x = 2x^{2}$, $2x\times(-5)=-10x$, $6\times x = 6x$, $6\times(-5)=-30$

Step3: Combine like - terms

$2x^{2}+(-10x + 6x)-30=2x^{2}-4x - 30$

Answer:

$2x^{2}-4x - 30$
