## michelle010d 2 years ago Find the smaller root for x^2− 4 = 0 .

1. petewe

Well, find the roots, which one is smaller?

2. campbell_st

then x^2 = 4 $x = \pm \sqrt{4}$ $x=\pm2$ you decide which is smaller...

3. michelle010d

when i plugd into 2 i said it waxs wrong

4. michelle010d

plugged* was*

5. petewe

you think 2 is greater than -2?

6. michelle010d

yeah

7. petewe

lord, help me now.

8. campbell_st

I hate these questions as the points have equal magnitude...

9. petewe

it's asking for the smaller root.

10. michelle010d

meaning?

11. petewe

so if 2 is greater than -2, which is smaller?

12. campbell_st
