Question

If * is an operation such that for integers 'a' and 'b' we have a b = axa + bxb-axb, then find
2*3​

Answer 1

Answer:

wait isn't 2×3 already solved?

Answer 2

Step-by-step explanation:

from given information 

a*b = a×b + (a×a + b×b)

so (-3)*(-5) = (-3)×(-5) + ((-3)×(-3) + (-5)×(-5))  = 15 + (9 +25)               

  = 15 + 34     

(-3)*(-5) = 49

(-6)*2 = (-6)×2 + ((-6)×(-6) + 2×2)       

  (-12) + (36 + 4)  = -12 + 40(-6)*2 = 28
