Simplify the rational expression. State any restrictions on the variablen^4-10n^2+24/ n^4-9n^2+18

Answers

Answer:

The simplified form is $=((n-2)(n+2))/((n-\sqrt3)(n+\sqrt3))$

The variable n can not be equals to $\pm\sqrt3$ as for these value denominator equals to zero which becomes an indeterminate form.

Step-by-step explanation:

we have to simplify the rational expression and state the restrictions on the variable.

$(n^4-10n^2+24)/(n^4-9n^2+18)$

We can now see that both the numerator and denominator are quadratic trinomials in $n^2.\$

We split the middle terms as follows;

$(n^4-10n^2+24)/(n^4-9n^2+18)=(n^4-6n^2-4n^2+24)/(n^4-3n^2-6n^2+18)$

$=(n^2(n^2-6)-4(n^2-6))/(n^2(n^2-3)-6(n^2-3))$

$=((n^2-4)(n^2-6))/((n^2-6)(n^2-3))$

$=((n-2)(n+2))/((n-\sqrt3)(n+\sqrt3))$

which is the simplified form of given expression.

The variable n can not be equals to $\pm\sqrt3$ as for these value denominator equals to zero which becomes an indeterminate form.

If 3a - 2 = 10, what is the value of 8a + 1?

Answers

Answer:

8a+1=33

Step-by-step explanation:

you can solve 3a-2=10 by simplifying to 3a=12, so a=4. Then you replace the a in 8a+1 with 4 to get 32+1, which is 33

Answer:

Step-by-step explanation:

3a-2= 10

3a=12

a=4

in this equation a=4 so you substitute that value into the other equation

8(4) +1=33

Suppose C and D represent two different school populations where C > D and C and D must be greater than 0. Which of the following expressions is the largest? Explain why. Show all work necessary.. . . (C + D)2. 2(C + D). C2 + D2. C2 − D2

Answers

Answer:

the largest is: $C^2+D^2$

Step-by-step explanation:

We are given the expression C>D>0.

As C and D represent two different school populations. This means that C and D will be natural numbers.

C+D<2×(C+D)

Also $C^2+D^2>C^2-D^2$ .

the largest among these expressions is $C^2+D^2$

The question or the problem wants to choose among the following expression is the largest, base on the data presented in the problem, the possible answer among the following choices is C2+D2. I hope you are satisfied with my answer and feel free to ask for more
