Hi there! The answer is A) x = 3 or x = 6

Divide by 2.

Factor.

Use the rule AB = 0 gives A = 0 or B = 0

The answer is A) x = 3 or x = 6
Suppose we have a generic equation of the form:
1) The first thing you must do to complete squares is to group similar terms of the form:
2) The second step is to complete the squares.
3) The third step is factor the quadratic equation
4) The fourth step is to identify the center and the radius
Answer:
the first step in finding the center of the circle by completing the square is:
C group like terms
Because the parabola intercepts the x-axis only once, we conclude that the discriminant is 0.

What can we say about the discriminant?</h3>
For a quadratic equation:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ac
- If D = 0, there is only one real zero.
- If D > 0, there are two real zeros.
- If D < 0, there are two complex zeros.
In the graph we can see that the parabola intercepts the x-axis in its vertex, then the parabola has only one real zero, then we conclude that the discriminant is equal to zero.
