Derivatives

Find the derivative of the function:

f(x)=2x^2-4x+3

The following rules are applied:

\begin{gathered} (x^n)^{\prime}=n\cdot x^{n-1} \\ (kx)^{\prime}=k \\ (k)^{\prime}=0 \end{gathered}

Where k and n are constants.

Applying the rules:

\begin{gathered} f^{\prime}(x)=2(2x)-4+0 \\ Operate\colon \\ f^{\prime}(x)=4x-4 \end{gathered}

Answer:

3/5

Step-by-step explanation:

I'm not completely sure but from what I see it says 'sin <em>C </em>' and both 12 , 20 are on C.

so i simply just did 12/20

reduced once - 6/10

reduced twice - 3/5

Which polynomial can be simplified to a difference of squares
Mrrafil [7]
<h2>Hello!</h2>

The answer is:

The polynomial that can be simplified to a difference of squares is the second polynomial:

16a^{2}-4a+4a-1=16a^{2}=(4a)^{2}-(1)^{2}=(4-1)(4+1)

<h2>Why?</h2>

To solve this problem, we need to look for which of the given quadratic terms given for the different polynomials can be a result of squaring (elevating by two).

So,

Discarding, we have:

The quadratic terms of the given polynomials are:

First=10a^{2}

Second=16a^{2}

Third=25a^{2}

Fourth=24a^{2}

We have that the coefficients of the quadratic terms that can be obtained by squaring are:

16a^{2} =(4a)^{2} \\\\25a^{2} =(5a)^{2}

The other two coefficients are not perfect squares since they can not be obtained by square rooting whole numbers.

So, the first and the fourth polynomial are discarded and cannot be simplified to a difference of squares at least using whole numbers.

Therefore, we need to work with the second and the third polynomial.

For the second polynomial, we have:

16a^{2} -4a+4a-1=16a^{2}=(4a)^{2}-(1)^{2} =(4-1)(4+1)

So, the second polynomial can be simplified to a difference of squares.

For the third polynomial, we have:

25a^{2} +6a-6a+36=16a^{2}+36=(5a)^{2}+(6)^{2}

So, the third polynomial cannot be simplified to a difference of squares since it's a sum of squares.

Hence, the polynomial that can be simplified to a difference of squares is the second polynomial:

16a^{2}-4a+4a-1=16a^{2}=(4a)^{2}-(1)^{2}
