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