Verified Answer :

  1. Find the greatest common factor (GCF)
    What is the largest number that divides evenly into 4x^2, -16x^4, and 10x^5?
    It is 2.
    What is the highest degree of x that divides evenly into 4x^2, -16x^4, and 10x^5?
    It is x^2.
    Multiply the results above, the GCF = 2x^2

    2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
    2x^2(4x^2/2x^2 + -16x^4/2x^2 + 10x^5/2x^2)

    3. Simplify each term in parentheses
    2x(2-8x^2+5x^3)

    Have a nice day :D
