Finding Zeros of a Quadratic Function by Factoring

This video tutorial teaches how to find the zeros of quadratic functions by factoring. It explains the process of rewriting functions in factored form and setting them to zero to find the input values that make the function equal to zero. The tutorial also covers common mistakes in factoring and how to verify zeros using graphs.

What is the first step in finding the zeros of a quadratic function in standard form?

• Add a constant to the function

• Set the function equal to 1

• Graph the function

• Rewrite it in factored form

When a quadratic function is factored, what do the zeros represent?

• The input values that make the function equal to zero

• The maximum points of the function

• The coefficients of the quadratic term

• The points where the graph intersects the y-axis

If a quadratic function is factored as (x + 4)(x - 1), what are the zeros?

• 0 and 4

• 4 and -1

• 1 and 4

• -4 and 1

What is a common mistake when identifying zeros from a factored form like (x - 2)(x - 3)?

• Using the quadratic formula

• Forgetting to set the equation to zero

• Graphing the function incorrectly

• Assuming the zeros are -2 and -3

In the function (x - 2)(x - 3), what are the correct zeros?

• -2 and -3

• 2 and 3

• 3 and -2

• 0 and 2
