If 2a+3b=12 and ab=6 find the value of 8a^3+27b^3

Alex17521 [72]

A) 2a + 3b = 12
B) ab = 6 solving for a
B) a = 6 / b then we substitute this into equation A)
A) 12 / b + 3b = 12 multiplying this by "b"
A) 12 + 3b^2 = 12b
A) 3b^2 -12b +12= 0 dividing by "3"
A) b^2 -4b + 4 = 0
Factoring
(b-2) * (b-2) = 0
b = 2
Since b = 2 then a = 3

NOW, we put these numbers into:
8a^3 +27b^3 
8*3*3*3 + 27*2*2*2
216 + 216
The answer is 512
