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

- Firejay5

@zordoloom Do you want to help

- experimentX

well ... solve it, you should get it.

- anonymous

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.

- Firejay5

How we don't solve it if it equals 0

- anonymous

Try using the quadratic formula.

- anonymous

a=1, b=4, and c=-4

Do you need exact answers, or would approximations suffice?

- Firejay5

I need help or at least a lead towards the answer

- Firejay5

matter of fact exact answers

I really don't know how you got -2 and 0.

- Firejay5

I think #32 is a no solution

- anonymous

The solution is above

nevermind

- anonymous

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.

- anonymous

"state the consecutive integers between which the roots are located."

- Firejay5

can you wait a second?

- anonymous

sure
