Hey there! I'm happy to help!
In the quadratic formula, the discriminant is square rooted. In this formula you have a ± before this radical. If the discriminant is positive, the solution can be either subtracting or adding the number, so there are 2 real solutions.
If it is 0, subtracting or adding are the same, so there will be just one solution.
You cannot have a negative square root. It is impossible with real numbers, so there are no real solutions.
I hope that this helps! Have a wonderful day! :D
The answer to the question is -9n - 6
A 10x7 =70 and u use i-ready cool
T=8√t
T=temperature
t=time in minutes.
If T=48, we have to calculate the time.
48=8√t
(48)²=(8√t)²
2304=64t
t=2304 / 64=36
answer: 48 degrees Celsius will be reached in 36 minutes.
