Given that the reciprocal of a equals itself, the absolute value of negative b is 3, and the opposite of c is 5 4Ab^2-6abc=? Given that the reciprocal of a equals itself, the absolute value of negative b is 3, and the opposite of c is 5,4ab^2-6abc=?

Given that the reciprocal of a equals itself, the absolute value of negative b is 3, and the opposite of c is 5 4Ab^2-6abc=? Given that the reciprocal of a equals itself, the absolute value of negative b is 3, and the opposite of c is 5,4ab^2-6abc=?

A =1/a
A =1 or a =-1
|B |=3 and b is negative
So b =-3
-C =5
C =-5
4Ab2-6abc
=2A (2b2-3bc)
=2A×[2×(-3)2-3×(-3)×(-5)]
=2A×(18-45)
=-54A
=54 Or -54
