Question

2\left(x^{2}-4x - 1\
ight)
which of the expressions below matches with the one above? (multiply inside terms with 2, or use desmos testing calculator)
\bigcirc\\ 2x^{2}-8x - 2
\bigcirc\\ x^{2}-8x - 2
\bigcirc\\ 2x^{2}-8x + 2
\bigcirc\\ 3x^{2}-5x - 1

Explanation:

Step1: Distribute 2 to $x^2$

$2 \times x^2 = 2x^2$

Step2: Distribute 2 to $-4x$

$2 \times (-4x) = -8x$

Step3: Distribute 2 to $-1$

$2 \times (-1) = -2$

Step4: Combine all terms

$2x^2 - 8x - 2$

Answer:

A. $2x^2 - 8x - 2$
