**Vectors: Dot product**

Given a and b unit vectors if |a+b|=square root 3, determine (2a-5b)dot(b+3a) First I foiled the whole thing: =2(a dot b)+ 6 (a dot a) - 5(b dpt b) -15(a dot b) =-13(a dot b) + 6(a dot a) - 5(b dot b) =-13(1)(1)+6-5 =-13+1 =-12 Textbook answer is -11/2 I don't know how to ...
