Question

question 6.
the sum of $2x^2 - x$ and $-7x + 1$ is equivalent to
2 $x^2$ (select) $x$ (select)
(select)
2
5
1

Explanation:

Step1: Write the sum expression

$(2x^2 - x) + (-7x + 1)$

Step2: Combine like terms for $x$

$2x^2 + (-x -7x) + 1 = 2x^2 -8x + 1$

Answer:

The coefficient for $x$ is $\boldsymbol{-8}$ (note: this value would be selected in the dropdown for the $x$ term; the coefficient for $x^2$ is already correctly set to 2)
