The values of a, b, and c in the equation x² + 6x - 55 = 0 are:
1, 6, and 55 respectively.
0, 6, and -55 respectively
.
1, 6, and -55 respectively.

value of a, b and c are 1, 6 and -55 respectively.

Last option is correct.

Step-by-step explanation:

We have been given the equation

The degree of the polynomial is 2 and hence, it represents a quadratic equation.

The general form of a quadratic equation is

On comparing this form with the given equation, we get

a = 1

b = 6

c = -55

Therefore, value of a, b and c are 1, 6 and -55 respectively

Last option is correct.

As we saw in Quadratic Functions , a parabola is the graph of a quadratic function. As part of our study of conics, we'll give it a new definition. A parabola is the set of all points equidistant from a line and a fixed point not on the line. The line is called the directrix, and the point is called the focus. The point on the parabola halfway between the focus and the directrix is the vertex. The line containing the focus and the vertex is the axis. A parabola is symmetric with respect to its axis. Below is a drawing of a parabola.
