Firejay5 Group Title

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

    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.

    Do you need exact answers, or would approximations suffice?

    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."
