take 1/2 of -5, and square it. Add that to both sides.

y+6.25= x^2 -ax + 6.25 +3
y+3.25= (x-2.5)^2

Now, looking at it, wouldn't it by symmetrical abouut x=2.5?

identify the axis of symmetry, create a suitable table of values y=x^2-5x+3

how do I do this Solve for x. 3x – 2y = 6 Add 2y to both sides and then divide both sides by 3, to give you just "x' on the left side. so is this how i work it out 3x-2y=6 3x- 2y= 6 -2y 3x=6-2y x= 2 +2y No. Add 2y to both sides.
