We need to find the roots of given quadratic equation using quadratic formula.
Quadratic formula for general quadratic equation 
is 
Here, for eqn (1) a = 6, b= -9 and c = 2
Hence the roots of are
The decimal form of 80% is . 80 meaning you have 80 parts of 100 so the fraction would be expressed as 80/100. Then this fraction can be further reduced, first I would devide both the numerator and denominator by ten so you are left with 8/10 which can be further reduced.
Answer: 80 dollars
Step-by-step explanation:
You can find a percentage with one of two ways.
For hundreds like this, oftentimes it's quicker and more simple to think of it as just 100. The proportion from 100 to 500 is just 5. 16% of 100 is 16. So, multiply 16 * 5. You would get 80.
The second method is you can use 0.16 * 500. It's the more conventional method, and you get 80, like the last method.
