Why are teacher giveign us so much homework if they dont even do homework
9 - x² < 0
<u>-9 -9</u> <u> </u><u /> to remove 9 deduct it from both sides<u></u>
- x² < -9
<u> ÷ -1 ÷-1 </u> to remove the negative sign, divide both sides by -1
x² < 9
<u> √x² < √9</u> to remove the exponent of 2, find the square root of both sides.
x < 3 Choice A.
To check:
9 - x² < 0
9 - 3² < 0
9 - 9 < 0
0 < 0
