### A110-4 solving factored polys

1. 1. Solving Polynomial Equations in Factored Form<br />Algebra 1<br />10.4<br />Using the Zero-Product Property<br />
2. 2. A polynomial is in factored form if it is written as the product of two or more linear factors.<br />
3. 3. A polynomial is in factored form if it is written as the product of two or more linear factors.<br />A linear factor has x to the power of one.<br />
4. 4. The zero-product property states:<br />If ab = 0, then a = 0 or b = 0.<br />
5. 5. Example<br />
6. 6. If one of these statements is true, all these statements are true:<br />
7. 7. If one of these statements is true, all these statements are true:<br />
8. 8. If one of these statements is true, all these statements are true:<br />
9. 9. If one of these statements is true, all these statements are true:<br />
10. 10. To graph an equation in factored form:<br />Solve the equation to find the x-intercepts.<br />
11. 11. To graph an equation in factored form:<br />Solve the equation to find the x-intercepts.<br />Find the coordinates of the vertex.<br />Remember x = -b/2a, plug in to find y.<br />
