    Then you do not use c at all The 4ac becomes 0 in the equation.

    out of my answer choices what would it be then? I'm confused at how you would plug it in and still get the answer

    x = 0, x = 5 x = 0, x = −5 x = −5, x = 0, x = 5 x = 5, x = 25

    -b\[\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]

    ax^2+bx+c so a=5 and b=25

    so it would be -25 =+/- sqrt of 25 all over 10

    \[\frac{ -25\pm \sqrt{25^2-4(5)(0)} }{ 2(5) }\] \[\frac{ -25\pm \sqrt{625} }{ 10 }\] \[\frac{ -25\pm25 }{ 10 }\] using addition it is \[\frac{ -25+25 }{ 10 }=0\] using subtraction it is \[\frac{ -25-25 }{ 10}=-5\]

    wait it is not square root of 25. You mean square root of 625 since it is b^2 not b
