Solve each equation by graphing. If exact roots can't be found, state the consecutive integers between which the roots are located. 22. x^2 + 4x - 4 = 0 I said the answer was -2 and 0 (-2, 0) <-- not coordinate point, I am not for sure if it's right or not

I know how to solve a quadratic equation
@zordoloom Do you want to help
well ... solve it, you should get it.
Sure, btw, the answer that you mentioned is not correct. As experimentX mentioned, solve it using the quadratic formula, and you should have the correct answer.
How we don't solve it if it equals 0
Try using the quadratic formula.
a=1, b=4, and c=-4

Do you need exact answers, or would approximations suffice?
I need help or at least a lead towards the answer
matter of fact exact answers

I really don't know how you got -2 and 0.
I think #32 is a no solution
The solution is above
|dw:1358103764172:dw|
nevermind
for #22, since it mentions to solve by graphing, it is a lot easier. just look at the graph and state between integer the graph intersects.
"state the consecutive integers between which the roots are located."
can you wait a second?
sure
thanks @zordoloom
