Subtract. 5x^2-5x+1-(2x^2+9x-6)
Talja [164]
<h2>Hello!</h2>

The answer is:

3x^{2} -14x+7

<h2>Why?</h2>

To solve the problem we need to add/subtract like terms. We need to remember that like terms are the terms that share the same variable and the same exponent.

For example, we have:

x^{2} +2x+3x=x^{2} +(2x+3x)=x^{2}+5x

We have that we were able to add just the terms that were sharing the same variable and exponenr (x for this case).

So, we are given the expression:

5x^2-5x+1-(2x^2+9x-6)=5x^{2}-2x^{2}-5x-9x+1-(-6)\\\\(5x^{2}-2x^{2})+(-5x-9x)+(1-(-6))=3x^{2}-14x+7

Hence, the answer is:

3x^{2} -14x+7

Have a nice day!

Oxana [17]

Answer:

\frac{16 {d}^{3} }{ {c}^{2} }

Step-by-step explanation:

{4}^{2}  {c}^{ - 2}  {d}^{3}  {e}^{0}

➡️ 16 {c}^{ - 2}  {d}^{3}  \times 1

➡️ 16 {c}^{ - 2}  {d}^{3}

➡️ 16 \times  \frac{1}{ {c}^{2} }  \times  {d}^{3}

➡️ \frac{16 {d}^{3} }{ {c}^{2} }
