Question

If * is an operation such that for integers a and b we have a*b = a×b+(a×a+b×b), then of 3 *(-5) is?​

Answer 1

Given, a∗b=a×b+(a×a+b×b)

So

we put a=(−3) and b=(−5)

(−3)∗(−5)=(−3)×(−5)+[(−3)×(−3)+(−5)×(−5)]

=15+(9+25)=15+34=49

Answer 2

Answer:

Given, a

∗

b=a×b+(a×a+b×b)

So.

(i)

we put a=(−3) and b=(−5)

(−3)∗(−5)=(−3)×(−5)+[(−3)×(−3)+(−5)×(−5)]

=15+(9+25)=15+34=49
