ANSWER:
<u>On solving equation by quadratic formula method, we get</u>
D = b² – 4ac
- (–5)² – 4 × 1 × 3
- 25 – 12
- 13
D > 0, so it has real roots.
Now, x = – b ± √D/2a
So, <u>Correct choice</u> - [A] & [C].
"27 percent" means 0.27
"of" means "times"
"27 percent of 300" means (0.27 x 300) = 81 .
At the beginning, you asked what percent this is.
81 is 8,100 percent .
