How do I find roots from a quadratic equation

Mathematics
1 answer:
Trava [24]3 years ago
6 0

Answer:The roots of any quadratic equation is given by: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.

Ellie practices piano 2/3 h per day, several days each week. She practiced piano 32/23 hours during the summer.
butalik [34]

Let us assume that the number of days she practiced the piano to be "d"

Since she practiced 2/3 hours a day, the total number of hours would be: 2/3*d

Now we are given the total number of hours during summer that she practiced  be be equal to 32/23

So we equate 2/3 * d to 32/23 to find d

2/3*d = 32/23

d = (32/23)/ (2/3)

d = (32/23) * (3/2)

d = 48/23 hours

The equation that can be used to find the number of days that she practiced piano during the summer is 2/3*d = 32/23
