I'm not bad at maths but haven't touched quadratics since A Level a VERY long time ago. Poor DD is doing them for GCSE (so much harder than it used to be but that's another thread).
She has a quadratic question which asks for the values of a and b where the curve has a turning point of (-3,-4) where a and b are integers and y=x(squared - can't find symbol,sorry) + ax +b.
I am a bit stumped how to do this - any ideas?
TIA
