1 What is the nature of the roots of the quadratic equation if the value of its discrimman is zero?
The roots are not real
o the roots are rational and not equal
b. The roots are irrational and not equal d the roots are rational and equal
2. Whal is the ans of symmetry of the parabola y

If d is zero, both roots are rational and equal.

Quadratic Equations

The standard representation of a quadratic function is:

where a,b, and c are constants.

Solving with the quadratic formula:

The discriminant is defined as:

The sign of the discriminant defines the nature of the roots of the quadratic equation as follows:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
