Given that
P(x)=64x3+96x2+44x+6P(x) = 64x^3 + 96x^2 + 44x + 6P(x)=64x3+96x2+44x+6
Use the factor theorem to prove that (4x+1)(4x + 1)(4x+1) is a factor of P(x)P(x)P(x).
Factorise P(x)P(x)P(x) completely.
Hence, prove that 128n3+192n2+88n+12128n^3 + 192n^2 + 88n + 12128n3+192n2+88n+12 is a multiple of 12 when nnn is a positive whole number.
