How to factor this problem with negative exponents? -4x^-4-3x^-2+1=0

Nat2105 [25]

$-4x^{-4}-3x^{-2}+1=0\\
-4x^{-4}-4x^{-2}+x^{-2}+1=0\\
-4x^{-2}(x^{-2}+1)+1(x^{-2}+1)=0\\
-(4x^{-2}-1)(x^{-2}+1)=0\\
4x^{-2}-1 =0 \vee x^{-2}+1=0\\
4x^{-2} =1 \vee x^{-2}=-1\\
x^{-2}=\frac{1}{4} \vee \frac{1}{x^2}=-1\\
\frac{1}{x^2}=\frac{1}{4}\\
x=-2 \vee x=2

If my wife owns 150 CDs and 20% of them are by boy bands - how many Boy band CDs does she own?

LuckyWell [14K]

You can use a calculator or you could change the percent to a fraction. 20% is equivalent to 20/100.

So just multiply 150 by 20 and divide that answer by 100 to get a number of 30 CDs of boy bands
