Answer:
y=5,2 and -3
we have to put the values of X and then solve the equation.
<h2>Have a good day</h2>
if a > 0, there are two possible solutions:

the square root of a square is the base in absolute value bars


if a = 0, that means x = 0. anything multiplied by 0 is 0
if a < 0, there are no solutions because anything squared has to be positive
The answer is A. -3x2 - 6x - 7
To find the average, combine all the numbers together and divide by the amount there is.
-7 + 2 - 9 - 4 - 7 = -25
-25/5 = -5
-5 is your average temperature
hope this helps
