    nope :P well the quadratic formula states that \(\huge x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \)

    ok so if you have \(\huge ax^2+bx+c=0 \) substitute the values of a b and c into the formula and solve it.

    To find x-intercepts put y =0 in y=x^2+2x-10

    you have an equation similar to ax^2+bx+c=0 substitute the values into the quadratic formula i gave you, and solve it algebraically

    i told you what a,b, and c are in that equation. a=1 b=2 c=-10 replace the values of a,b and c into the quadratic formula i gave you and solve it to find x
