Question

Choose the LCM of x3 + 8, x2 + 5x + 6 and 12 + 4x2 + 4x.
(A) x(x + 2)? (x + 3) (x2 – 2x + 4)
(B) x(x - 2)? (x – 3) (x2 + 2x + 4)
(C) x(x - 2)? (x – 3) (x2 + 2x + 4)
(D) (x - 2)? (x + 3) (x2 – 2x + 4)​

Answer 1

Answer:

(A) x(x + 2)? (x + 3) (x2 – 2x + 4)

Step-by-step explanation:

x^3+8=x^3+2^3=(x+2)(x^2-2x+4)

x^2+5x+6=(x+3)(x+2)

4x^2+4x+12=4(x^2+x+3)
