f(x)=64x^4-192x^3+x^2-3x

Question

please solve

 

Answer 1

f(x)=64x⁴-192x³+x²-3x=x(64x³-3*64x²+x-3)=x[64x²(x-3)+(x-3)]=x(x-3)(64x²+1)

Answer 2

f(x) = 64x^4 - 192x^3 + x^2 - 3x

 

f(x) = x(64x^3 - 192x^2 + x - 3)

 

f(x) = x( 64x^2(x - 3) + 1(x - 3) )

 

f(x) = x(x - 3)(64x^2 + 1)

 

f(x) = x(x - 3)((8x)^2 – (i^2))

 

f(x) = x(x - 3)(8x – i)(8x + i)
