Step 1: Given Expression to simplify is
$\left({x}^{3}-{x}^{2}-2x\right)-\left(-11{x}^{4}-9x-6\right)$
We need to subtract the polynomials.
Formula used:
-(-a)=a
Step 2: On simplifying using the expansion of brackets,
${x}^{3}-{x}^{2}-2x+11{x}^{4}+9x+6$
$⇒11{x}^{4}+{x}^{3}-{x}^{2}-2x+9x+6$
$⇒11{x}^{4}+{x}^{3}-{x}^{2}+7x+6$
The above expression is the answer we get after subtraction.
