Question

Find the LCM of the given polynomials. x^2 - 25 and x^2 - 3x - 10

Answer 1

x^2 - 25 equals (x - 5) x (x + 5)

x^2 - 3x - 10 equals (x + 2) x (x - 5)

Explanation:

For x^2 - 25

x^2 - 5^2

(x - 5) x (x + 5)

For x^2 - 3x - 10

x^2 + 2x - 5x - 10

x x (x + 2) - 5x - 10

x x (x + 2) x (x - 5)
