Step-by-step explanation:
quadratic formula
<u>-b+-√b^2</u>
<u>2</u><u>a</u>
<u>-</u><u>2</u><u>+</u><u>-</u><u>√</u><u>2</u><u>^</u><u>2</u><u>-</u><u>4</u><u>×</u><u>1</u><u>×</u><u>-</u><u>1</u><u>6</u>
2×1
<u>-2+-√68</u>

either
x= 3.125
or
x= -5.125
12% of 72 is:
=12×72/100
=8.64
So the 12% of 72 is 8.64 is your answer.
