u = <-6,1>
-4u = -4*<-6,1>
-4u = <-4*(-6),-4*1>
-4u = <24,-4>
----------------------
v = <-5,2>
2v = 2*<-5,2>
2v = <2*(-5),2*2>
2v = <-10,4>
----------------------
-4u + 2v = <24,-4> + <-10,4>
-4u + 2v = <24+(-10),-4+4>
-4u + 2v = <24-10,-4+4>
-4u + 2v = <14,0>
----------------------
Answer: B) <14,0>
