    Are we supposed to factor this?

    Subtract 10 from both sides. \[\huge~\rm~x^2+3x−10=10−10\] \[\huge~\rm~x^2+3x−10=0\]Factor left side of equation. \[\huge~\rm~(x−2)(x+5)=0\]

    From here solve for x x-2=0 x=? x+5=0 x=?

    How did you get five if we subtract a 3 -10?

    (x−2)(x+5)=0 x-2=0 to solve we add 2 to both sides because we are isolating x x=2 now try x+5=0
