Step 1: Calculate the points of intersection for 5.1.1.
To find the points of intersection, set the two equations equal to each other:

3x−2x2=12x3x - 2x^2 = \frac{1}{2}x

Multiply by 2 to clear the fraction:

6x−4x2=x6x - 4x^2 = x

Rearrange the terms to form a quadratic equation:

4x2−5x=04x^2 - 5x = 0

Factor out xx:

x(4x−5)=0x(4x - 5) = 0

This gives two possible values for xx:
