Check your question once again..

anonymous · Answer

What do you mean? I copied and pasted the question so i know its right.

anonymous · Answer

Okay okay now I got it..

anonymous · Answer

$$y = 4x^2 + 2x - 12x -6$$

So:

$$\large y = 4x^2 - 10x - 6$$

Can you tell what is the coefficient of x term here??
