Step 1: Given Expression to simplify is

$({x}^{3}-{x}^{2}-2x)-(-11{x}^{4}-9x-6)$

We need to subtract the polynomials.

Formula used:

-(-a)=a

Step 2: On simplifying using the expansion of brackets,

${x}^{3}-{x}^{2}-2x+11{x}^{4}+9x+6$

$\Rightarrow 11{x}^{4}+{x}^{3}-{x}^{2}-2x+9x+6$

$\Rightarrow 11{x}^{4}+{x}^{3}-{x}^{2}+7x+6$

The above expression is the answer we get after subtraction.

Determine whether the following function is a polynomial function. If the function is a polynomial function, state its degree. If it is not, tell why not. Write the polynomial in standard form. Then identify the leading term and the constant term.

$g(x)=3-\frac{{x}^{2}}{4}$

Use the grouping method to factor the polynomial in the box completely. Use the caret symbol ( ^ ) to write exponets; for example enter $x}^{2$ as $x}^{2$ . Write each factor as a polynomial in descending order. $6{x}^{5}+36{x}^{2}+24x$
