A^2 + 3b/a - a
Substitute a=0.6 and b=2 into the expression:
(0.6)^2 + 3(2)/0.6 - 0.6= 0.36 + 6/0.6 - 0.6= 0.36 + 10 - 0.6= 10.76
Therefore, when a=0.6 and b=2, the value of the expression A^2 + 3b/a - a is 10.76.
A^2 + 3b/a - a
Substitute a=0.6 and b=2 into the expression:
(0.6)^2 + 3(2)/0.6 - 0.6
= 0.36 + 6/0.6 - 0.6
= 0.36 + 10 - 0.6
= 10.76
Therefore, when a=0.6 and b=2, the value of the expression A^2 + 3b/a - a is 10.76.
