Find the LCM of the polynomials. 2x - 4, 5x - 10
Marizza181 [45]

Answer:

10x - 20

Step-by-step explanation:

First, factor both polynomials.

2x - 4 = 2(x - 2)

5x - 10 = 5(x - 2)

The LCM is the product of the common and not common factors with larger exponent.

LCM = 2 * 5 * (x - 2)

LCM = 10(x - 2) = 10x - 20
