Factor out the GCF from the polynomial. -3x⁴ + 12x³ – 21x²

Factor out the GCF from the polynomial. 10a²b + 12ab²

Find the GCF of this pair of monomials. 8a² and 28a⁵

Find the GCF of this pair of monomials. 10x and 25

Since x is not common in both the GCF in question will be the GCF of 10 and 25.
