Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)

Step-by-step explanation:
substitute the given values for x and y into the expression
4x² + 2y
= 4(3)² + 2(
)
= 4(9) + 1
= 36 + 1
= 37
