## anonymous 4 years ago quadratic function in standard form

1. anonymous

|dw:1327784272424:dw| express in standard form

2. myininaya

$y=ax^2+bx+c \text{ is standard form }$

3. anonymous

= x^2 - 4x + 4 + 4 = x^2 - 4x + 8

4. myininaya

$y=(x-2)(x-2)=x(x-2)-2(x-2)$ do a little more distributing and then combine like terms and you will have it

5. myininaya

8?

6. myininaya

$y=x^2-2x-2x+4=x^2-4x+4$

7. myininaya

oh sorry my screen cut that +4 off lol

8. myininaya

jimmy is right

9. anonymous

ok - lol

10. myininaya

i had my screen minimized so i was just seeing y=(x-2)^2

11. anonymous
