Question

Solve the Inequality: shome me the steps please
( -5)/(4-x^2) ≥0

Answer 1

Show me**

Answer 2

look at the denominator solve 4 - x^2 = 0, x= 2 pr -2

values larger than 2, or -2 give a negative denominator... and with a negative numerator will result in a positive number... so

x>= 2 or x<= -2

Answer 3

\[-20+5x^2\ge0\]
\[5x^2\le20\]\[x^2=20/5\]
\[x^2=4\]
\[x=\sqrt{4}\]
\[x=\pm2\]
