You need to evaluate the product of the vectors `u = u_x*i + u_y*j, v = v_x*i + v_y*j` , such that:
`u*v = u_x*v_x + u_y*v_y`
`u*v = (3)*(-2) + 2*(-3)`
`u*v = -6 - 6`
`u*v = -12`
Hence, evaluating the product of the vectors `u = u_x*i + u_y*j, v = v_x*i + v_y*j,u = <3,2>, v = <-2,-3>,` yields `u*v = -12.`
