UWAAAAA FINALLYY I GET IT 😭😭😭😭😭

[@mathsunboxed]

Yess! Great work🙌

[@nigel198]

beest teacher no cap

[@JohnCena-bo7bm]

For the turning point. Don’t you just do -b divide by 2a

[@msprofesor]

you got pretty hands

[@bismarkarthur9039]

❤️❤️✌️

[@mohammedsalim6868]

but i think you made a small mistake on -6 square is 36 not -36

[@mathsunboxed]

Thanks for your comment! I think the bit you’re referring to is where it’s -(6 squared) = -36 (You’re right that if it was (-6) squared then that is 36😊) Remember by BIDMAS even if there are no brackets then we still do the power before taking the negative. Hope that helps!
