Question

y = x^2 + 2x + 1
I just need to find the two x- intercepts. I solved it and received x = -1 for both I need some help.

Answer 1

welll lets see...using the quadratic formula we have

\[-2 \pm \sqrt{2^{2} - 4(1)(1)} / 2(1)\]

so -2 plus/minus 4-4 all over 2

-2 plus or minus 0 all over 2

*******************************************
\[\sqrt{b ^{2}-4ac}\]
when this part = 0....there is ONLY 1 root....so there is ONLY 1 answer here...which you have :)
