How do you find the zeros/solutions of a quadratic function from its graph?

Back

The solutions are the x-values where the graph intersects the x-axis. In this case, the answer is 'Empty Set. Does not equal zero.'

Front

What does it mean for a quadratic function to have no real solutions?

Back

It means the graph of the function does not intersect the x-axis, indicating that the discriminant is negative.

Front

How do you factor a quadratic expression?

Back

To factor a quadratic expression, find two numbers that multiply to the constant term and add to the coefficient of the linear term.
