Question : If $x+\frac{1}{x}=-2$, then what is the value of $x^{17}+x^{-17}+x^{12}+x^{-12} ?(x<0)$
Option 1: –2
Option 2: –1
Option 3: 1
Option 4: 0
Correct Answer: 0
Solution : Given $x+\frac{1}{x}=-2$ $⇒x^2+1=-2x$ $⇒x^2+2x+1=0$ $⇒(x+1)^2=0$ $⇒x=-1$ Now, putting the value of $x=-1$ in $x^{17}+x^{-17}+x^{12}+x^{-12}$ we get: $=(-1)^{17}+(-1)^{-17}+(-1)^{12}+(-1)^{-12}$ $=-1-1+1+1=0$ Hence, the correct answer is 0.

Question : If $a+b+c=5, a^3+b^3+c^3=85$, and $abc=25$, then find the value of $a^2+b^2+c^2-a b- bc - ca$.
Option 1: 2
Option 2: 4
Option 3: 6
Option 4: 8
Correct Answer: 2
Solution : $a+b+c=5$ Squaring both sides, ⇒ $(a+b+c)^2 = 25$ ⇒ $a^2 + b^2 + c^2 +2(ab+bc+ca) = 25 $ ⇒ $a^2 + b^2 + c^2 - ab - bc - ca + 3(ab+bc+ca) = 25$ ........(1) Now we have to find the value of $(ab +
