## Firejay5 2 years ago 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

1. experimentX

do you know how to factorize?

2. Firejay5

Do you have a graphing calculator?

3. experimentX

i don't have graphing calculator ... do you know how to solve quadratic equation? or do you know how to factorize?

4. Firejay5

I know how to solve a quadratic equation

5. Firejay5

@zordoloom Do you want to help

6. experimentX

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

7. zordoloom

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.

8. Firejay5

How we don't solve it if it equals 0

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

Do you need exact answers, or would approximations suffice?

16. zordoloom

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

17. Firejay5

I think #32 is a no solution

18. zordoloom

The solution is above

nevermind

21. zordoloom

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.

22. zordoloom

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

23. Firejay5

can you wait a second?

24. zordoloom

sure

thanks @zordoloom
