Find the standard form of the following equation. y=(x+3)^2+1 Pls Help

OpenStudy (luigi0210):

Standard form is \(\large Ax^2+Bx+C\)

OpenStudy (luigi0210):

*\(\large =y\)

OpenStudy (anonymous):

\[ y=x ^{2}+9x+1?\]

OpenStudy (luigi0210):

No, you made a common booboo >.<

hero (hero):

y = (x + 3)(x + 3) + 1

hero (hero):

Try Foiling (x + 3)(x + 3) first

OpenStudy (luigi0210):

\((a+b)^2 \neq a^2+b^2\)

OpenStudy (anonymous):

ohh ok so that would make it \[y=x ^{2}+3x+9?\]

OpenStudy (luigi0210):

And then +1

OpenStudy (anonymous):

making it \[y=x ^{2}+3x+10?\]

OpenStudy (luigi0210):

Yup~

OpenStudy (luigi0210):

Wait, check your middle term.

OpenStudy (anonymous):

\[6x\]

OpenStudy (luigi0210):

Now it's right :)
