Question

resolve into factors :54x^4 +27(x^3)a-16x-8a​

Answer 1

Step-by-step explanation:

$54 {x}^{4} + 27 {x}^{3}a - 16x - 8a \\ \\ 27 {x}^{3} (2 {x} + a) - 8(2x + a) \\ \\ (2x + a)(27 {x}^{3} - 8)$

Answer 2

Answer:

(2x--a)(3x-2)(9x^2+4+6x)

Step-by-step explanation:

=54x^4+27x^3a-16x+8a

=27x^3(2x-a) -8(2x-a)

=(2x-a)(27x^3-8)

=(2x-a)(3^3x^3-2^3)

=(2x-a)({3x}^3-2^3)

=(2x-a)(3x-2)({3x}^2+2^2+3x×2)

=(2x-a)(3x-2)(9x^2+4+6x)
