We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:

b = coefficient of x term = 4
a = coefficient of squared term = 1
c = constant term = 7
Using the values, we get:
So, the correct answer to this question is option A
Answer:
B) {-8,-1,0,6)
Step-by-step explanation:
range is always y
X^2-18 = 3x
x^2 - 3x - 18 = 0
(x-6)(x+3) = 0
x = {-3,6}
So -3 is the answer
It's C I looked it up for you I promise it's right :D
Answer:
I'd say multiply the numerators then the denominators and at the end simplify at least thats how I multiply fractions :)
