Question

question
express as a trinomial.
$(2x + 6)(2x + 8)$
answer
attempt 1 out of 2

Explanation:

Step1: Use FOIL method

$(2x + 6)(2x + 8)=2x\times2x+2x\times8+6\times2x + 6\times8$

Step2: Calculate each term

$2x\times2x = 4x^{2}$, $2x\times8=16x$, $6\times2x = 12x$, $6\times8 = 48$

Step3: Combine like - terms

$4x^{2}+(16x + 12x)+48=4x^{2}+28x + 48$

Answer:

$4x^{2}+28x + 48$
