How do you find the zeros in the equation: x^3-x^2-5x+2 in a graphing calculator
graph the equation. Zeroes are when the function is on the x axis.
To find the zeros of the equation x^3 - x^2 - 5x + 2 using a graphing calculator, you can follow these steps:
1. Turn on your graphing calculator and go to the function menu.
2. Enter the equation: y = x^3 - x^2 - 5x + 2.
3. Plot the graph by pressing the graph or plot button.
4. Look for the x-intercepts or zeros of the equation, which are the points where the graph intersects the x-axis.
5. You can use the "zero" or "intersect" function on your calculator to locate these points. Refer to your calculator's user manual for specific instructions on how to use these functions.
6. Once you have found the x-coordinates of the zeros, you can write them down as solutions to the equation.
Remember, a graphing calculator is a useful tool for visualizing and finding solutions, but it's always a good practice to verify the calculated zeros by factoring or using other algebraic methods.
