Hi there, I have two problem that I just can't seem to figure out. They are as follows (1) Find the equation of the normal to $\displaystyle y= x^2-3x+2$ which have a gradient of $\displaystyle {\frac{1}{2}}$ and the second one(2) find the value of K for which $\displaystyle y=2x +k$ is a normal to $\displaystyle y= 2x^2-3$.

Can some one please help me with this? Thank you very much in advance.
