Answer:
The roots of the equation is real and repeated
Step-by-step explanation:
Here, we want to describe the nature of the roots of the given quadratic equation
To get the nature of the roots, we find the discriminant of the equation
The discriminant is;
b^2 - 4ac
In this case, b = -28 , a = 49 and c = 4
The discriminant is thus;
-28^2 - 4(49)(4)
= 784 - 784 = 0
Since the discriminant is zero, this means that the quadratic equation has real roots which are the same
Answer:
54.5
Step-by-step explanation:
Answer:
A. 0 and 6
Step-by-step explanation:
We look for values of x that make the numerator zero be letting the numerator equal 0.
8x(x - 6) = 0
8x = 0 or x - 6 = 0
x = 0 or x = 6
The denominator excludes x = -2 and x = -9 from the domain, but since the zeros are not those values, the values excluded from the domain do not affect the zeros of the function.
Answer: A. 0 and 6
