Question

convert to standard form
2(x + 1)(x + 3)

Explanation:

Step1: Expand using FOIL

First expand \((x + 1)(x + 3)\):
\((x+1)(x + 3)=x\times x+x\times3+1\times x + 1\times3=x^{2}+3x+x + 3=x^{2}+4x + 3\)

Step2: Multiply by 2

Multiply the result by 2:
\(2(x^{2}+4x + 3)=2x^{2}+8x+6\)

Answer:

\(2x^{2}+8x + 6\)
