Question

Multiplying \(x\) with the sum of \(11x^2-8x+4\) and \(6x^2+7x-10\) gives:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

$11x^2-8x+4$
$\underset{–}{6x^2+7x-10}$
$17x^2-x-6$

We multiply the above by $x$.

i.e. $x(17x^2-x-6)$ = $x\left(17x^2\right)-x\left(x\right)-x\left(6\right)$

= $17x^3-x^2-6x$
