Factor completely 16x8 − 1.
marta [7]

<u>Given</u>:

The given expression is 16 x^{8}-1

We need to determine the factor of the given expression.

<u>Factor</u>:

Let us rewrite the given expression.

Thus, we have;

\left(4 x^{4}\right)^{2}-1^{2}

Since, the above expression is of the form a^2-b^2, let us apply the identity a^2-b^2=(a+b)(a-b)

Thus, we have;

\left(4 x^{4}+1\right)\left(4 x^{4}-1\right) ------ (1)

Now, we shall factor the term 4x^4-1

4x^4-1=(2x^2)^2-1^2

           =(2x^2+1)(2x^2-1)

Substituting the above expression in equation (1), we have;

\left(4 x^{4}+1\right)\left(2 x^{2}+1\right)(2x^2-1)

Therefore, the factor of the given expression is \left(4 x^{4}+1\right)\left(2 x^{2}+1\right)(2x^2-1)

Hence, Option B is the correct answer.

PLZ HELP ME BY THE END OF THE DAY
nlexa [21]

3x^{2} +1=28

Step 1 : subtract 1 from both sides

3x^{2} =27

Step 2 : Divide both sides by 3

\frac{\frac{3x^{2} }{3} }{\frac{27}{3} }

x^{2} = 9

Step 3 : Find the square root of 9

\sqrt{9} = 3

x= (-3,3)

remember negative × negative = positive
