Find the LCM of the polynomials. 2x - 4, 5x - 10

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

10 (x-2)

Step-by-step explanation:

2x - 4

5x - 10

factor both

2 (x - 2)

5 (x - 2)
