Question

Find the GCF
`14u^2+35u^4`

Answer 1

7u²

Explanation:

14u² can be written as 2 × 7 × u × u

35u⁴ can be written as 5 × 7 × u × u × u × u

The greatest common factor is 7 × u × u.

Answer 2

If we look at the coefficients, 14 and 35 have a GCF of 7. The GCF of u² and u⁴ is u² so the answer is 7u².
