Question

Describe how factoring can help you find the x-intercepts of the graph of the quadratic function y=x^2 - 4x +3.The x-intercepts are the x-values where y=____ .So to find these x-values, you can apply the____ property and set each factor equal to _____.The x-intercepts are the solutions to the resulting equations.

Answer 1

Given the function:

`y=x^2-4x+3`

• The x-intercepts are the x-values where ,y=0,.

,

• So to find these x-values, you can apply the ,factorization, property and set each factor equal to ,0,.

,

• The x-intercepts are the solutions to the resulting equations.
