Answer 1

Given that we have to write the quadratic equation and then we have to solve it and represent it graphically.

Then,

let the equation be

$x^2+10x-24=0$

To find the roots we will do the factorization then we have

$\begin{gathered} x^2+10x-24=0 \\ x^2+12x-2x-24=0 \\ x(x+12)-2(x+12)=0 \\ (x+12)(x-2)=0 \\ x+12=0\text{ and x-2=0} \\ x=-12\text{ and x = 2} \end{gathered}$

So the roots are -12 and 2.
