$\left(9b^2-6b+1\right)-5-1=\left(3b-1\right)^2-6$

$\left(3b-1\right)^2-\left(\sqrt{6}\right)^2=\left(3b-1-\sqrt{6}\right)\left(3b-1+\sqrt{6}\right)$

Let v be the set of all ordered pairs of real numbers and consider the scalar addition and multiplication operations defined by: u+v=(x,y)+(s,t)=(x+s+1,y+t -two) au=a.(x,y)=(ax+a-1,ay-2a+2) It is known that this set with the operations defined above is a vector space. A) calculate u+v is au for u=(-2,3),v=(1,-2) and a=2 B) show that (0,0) #0 Suggestion find a vector W such that u+w=u C) who is the vector -u D) show that axiom A4 holds:-u+u=0
