Find the least common multiple of x^2+x-12 and x^2+2x-15

a. (x+4)(x-3)(x+5)
b. (x-3)(x+5)(x-4)
c. (x+4)(x-3)(x-3)
d. (x+4)(x-5)(x-3)

First factorize the given quadratics as much as possible:

Both share a common factor of . We have to multiply the first by and the second by in order to get a new expression that involves all the factors of both, so that the LCM is

making the answer A.

i think the correct option is the second option.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
