Question

If # is an operation such that for any integers a
and b, we have: a#b= a × b-
2 × a × b + b × b (-a)×b+b×b
then find (a)4#(-3) (b)(-7)#(-1)​

Answer 1

Answer:

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
