2x
4x
6x
4
To find the greatest common factor (GCF) of a polynomial, we need to find the common factors of all the terms and then identify the largest factor.
Let's factor out the common factor of the given polynomial, 4x^4 + 12x^3 - 36x^2 + 24x:
4x(x^3 + 3x^2 - 9x + 6)
Now, let's factor each term within the parentheses:
4x(x^3 + 3x^2 - 9x + 6) = 4x((x^3 + 3x^2) + (-9x + 6))
Next, we can factor out the common factors within each pair of terms:
4x(x^2(x + 3) - 3(x - 2))
Now, we can rewrite the polynomial using the factored form:
4x(x^2(x + 3) - 3(x - 2)) = 4x(x^2(x + 3) - 3(x - 2))
Thus, the GCF of the polynomial 4x^4 + 12x^3 - 36x^2 + 24x is 4x.
