Question 93497: Hello out there,I really need some help really bad with some tough problems,The first one is,Solve x^2+7x-8=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.The next one is,Solve -x^2+6x-5=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.The third one is,Solve x^2+6x-2=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.And the last one is,Solve x^2-4x+3=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located,thanks to whoever can help.

You can put this solution on YOUR website!
The first one is,Solve x^2+7x-8=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.
You can graph these by finding 3 points and drawing a parabola thru them.
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cx%5E2%2B7x-8%29
Answers: x=-8 x=1
---------------------
Solve -x^2+6x-5=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C-x%5E2%2B6x-5%29
Answers: x = 1 x=5
---------------------
Solve x^2+6x-2=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cx%5E2%2B6x-2%29
Answers: x between -7 and -6; x between 0 and 1
-------------------
Solve x^2-4x+3=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located,
I'll leave this one to you.
