When you are solving a non factorable quadratic equation, what is the very first step you need to do?

Step-by-step explanation:

Try first to solve the equation by factoring. Don't waste a lot of time trying to factor your equation; if you can't get it factored in less than 60 seconds, move on to. Don't forget to include a ± sign in your equation once you have taken the square root

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
