Question

What is the quadratic formula used for? How can you make sure your solution is correct?

t. Describe the quadratic formula in general (using constants a, b and c) then use the general form to find the x-intercepts of this particular parabola.

 

(Please provide work) Very appreciated!

Answer 1

The quadratic formula is the way to solve a quadratic equation (sometimes there's an easier way, if the equation is factorable.)

 

You have not provided any particular equation, so that's all that we can do for you here.

 

Zeros of a quadratic function give the x intercepts of the parabola; these are also known as the roots of the equation when the quadratic is set to 0.
