Find the L. C.M of x^2+x , x^2-1 , x^2-x

Step-by-step explanation:

To find the LCM of any integer, we take the product of all the highest powers of the factors that appear in the numbers. Factoring our three given expressions gives us the products

Our LCM will be a product of some powers of , , and . The most each factor occurs in the three expressions is once, so our least common multiple is

which can be simplified to

Step-by-step explanation:

x² + x = x * (x + 1)

x² - 1  = (x - 1)(x + 1)                      {a² - b² = (a+b)(a-b)}

x² - x = x * (x - 1)

LCM = x * (x + 1) * (x - 1)

a is the right answer

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
