## anonymous one year ago Find the x-intercepts of the graph of the equation: y = x^2 - 3x + 2 hmm so i got x=2, and x=1 which doesn't make sense

1. ganeshie8

why ?

2. anonymous

well when i plugged the numbers in it wasn't equivalent

3. freckles

$2^2-3(2)+2=0 ? \\ \text{ well } 2^2-3(2)+2=4-6+2=-2+2=0 \\ \text{ so } 2^2-3(2)+2=0 \text{ is a true equation }$

4. freckles

and you can check the other one in a similar way

5. freckles

you should get $1^2-3(1)+2 \text{ is also } 0$

6. anonymous

oh wait so i got it right....

7. freckles

yes the x-intercepts are (2,0) and (1,0)

8. freckles

you solved 0=x^2-3x+2 correctly

9. anonymous

OMG!!!! proud moment :P

10. freckles

you did good! :)
