Answer:
The second option is correct.
Step-by-step explanation:
The given expression is
[tex]10x^5+4x^4+8x^3[/tex]
The factors of first term is
[tex]10x^5=2\times 5\times x\times x\times x\times x\times x[/tex]
The factors of second term is
[tex]4x^4=2\times 2\times x\times x\times x\times x[/tex]
The factors of third term is
[tex]8x^3=2\times 2\times 2\times x\times x\times x[/tex]
The common factors are 2,x,x and x, therefore the greatest common factor is [tex]2x^3[/tex].
[tex]2x^3(5x^2+2x^2+4)[/tex]
Therefore the second option is correct.
