(8)/(27)x^(3)+1+(4)/(3)x^(2)+2x

Factorize: 8/(27)x^3+1+4/3x^2+2x

If (sin^(4)x)/(2)+(cos^(4)x)/(3)=(1)/(5) then tan^(2)x=(2)/(3)(b)(sin^(8)x)/(8)+(cos^(8)x)/(27)=(1)/(125)tan^(2)x=(1)/(3)(d)(sin^(8)x)/(8)+(cos^(8)x)/(27)=(2)/(125)

((6x^(4)+8x^(3)+27x^(2)+7)/(3x^(2)+4x+1))

If ((9)/(4))^(x)xx((8)/(27))^(x-1)=(2)/(3), then the value of x is a.1 b.2 c.3 d.4
