Isiah determined that 5a2 is the GCF of the polynomial
a^3 – 25a^2b^5 – 35b^4. Is he correct?

Isiah determined that 5a2 is the GCF of the polynomial  a^3 – 25a^2b^5 – 35b^4-No,Isiah is not correct if he states that that 5a2 is the GCF of the polynomial

Step-by-step explanation:

Firstly ,we divide each term by the GCF and if the term does not divide evenly, then it is not valid

so,

5a^2 divide by a^3

we see that we cannot  divide 5a^2  by a^3  because firstly  the power is higher and then  there is no 5 number.Thus  it is not the GCF

The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial.

Also we find that 5b^4 is a factor of -25a^2b^5 and -35b^4, but not a3. Additionally, a2 is a factor of a3 and -25a^2b^5, but not -35b^4.
