A=8-b c=ab-16 how many are a, b, c (abc is a rational number) A=8-b c=ab-16 Ask how much a, b, c are (abc is a rational number)
Given that a, b, c are rational numbers and satisfy a=8-b, c^2=ab-16, find the value of a, b, c,
Bring a=8-b into the second formula
C^2= b (8-b)-16
C^2=8b-b^2-16
=-(B^2-8b+16)
=-(B-4)^2
Because c^2>=0 and (b-4)^2>=0
So, above all,
B-4=0
B=4
So c=0 a=4
