Can anyone factorise y=-4x²-19x+63 for me please?
Yep, i’m back again.
As pathetic as it may sound I am unable to factorise this equation. This mean put it into 2 bracets as in (x+1)(x-5).
Please help.

y=-4x²-19x+63
y = (-4x + 9)(x + 7)

Start by looking at the possibles – 63 has to be either -9*-7 or 9*7. -4x² has to be -x*4x,-2x*2x or -4x*x. -19 can only be
-28+9. then you put the pieces together
Always analyse what you know – then the answer is easy.

The answer you want should be
y=(x-2.375)(x-2.375)
