D>0, there are 2 distinct real roots
Explanation:
3x2+6x−2=0
a=3,b=6,c=−2
The formula for discriminant is b2−4acSubstitute the given values.
b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots
Answer:
see the explanation
Step-by-step explanation:
Let
x ------> the next grade
we know that
To find the average grade sum the grades by the number of math test
so

solve for x
Combine liker terms in the right side

Multiply by 5 both sides

Subtract 372 both sides

-----> this is not make sense
The grade cannot be a negative number
so
For x=0
The minimum average grade is
