not knowing what kind of calculator you have, it might be difficult to answer your question.

Using a ti-84+, enter the equation using the

**y=** key

press the

**graph **key.

Press

**2nd** and then the

**trace** key to bring up the

**calc** menu.

Choose

**2: Zero**
using the left arrow key, move the 'spider' to just above the left x-intercept and press

**enter** to mark the

**left bound** side of your zero, then move the spider just below the x-intercept and press

**enter **to mark the

**right bound** side of your zero. Press

**enter** once more to reveal the zero (x-intercept).

You should've gotten

**-.6513878**
that's rounded off, because the exact answer is irrational. Use the quadratic formula to verify this.

You need to repeat this process for the other zero.

By the way, the

**spider** is that blinking asterisk of a thing that is tracing the curve when you use the left or right arrow keys.
