Simplify the rational expression. State any restrictions on the variable.
ExtremeBDS [4]

we are given

\frac{(n^4-10n^2+24)}{(n^4-9n^2+18)}

Firstly, we will factor numerators and denominators

\frac{(n^4-10n^2+24)}{(n^4-9n^2+18)}=\frac{(n^2-6)(n^2-4)}{(n^2-3)(n^2-6)}

we can see that

n^2 -6 is factor on both numerator and denominator

so, it will get cancelled

and n^2 -6 can not be equal to 0

so, one of restriction is

n^2-6\neq 0

n\neq -+ \sqrt{6}

we can simplify it

\frac{(n^4-10n^2+24)}{(n^4-9n^2+18)}=\frac{(n^2-4)}{(n^2-3)}

we know that denominator can not be zero

n^2-3\neq 0

n\neq -+ \sqrt{3}

so, option-B.......Answer

How do you solve 4s+5=19
kolbaska11 [484]
4s + 5 = 19

First, subtract 5 from both sides. / Your problem should look like: 4s = 19 - 5.
Second, simplify 19 - 5 to 14. / Your problem should look like: 4s = 14.
Third, divide both sides by 4. / Your problem should look like: s = \frac{14}{4} . 
Fourth, simplify \frac{14}{4} to \frac{7}{2} . / Your problem should look like: s = \frac{7}{2} which is the answer.
