LCM of x²+5x+6 and x²-x-6 is ………………………

Step-by-step explanation:

Given:

Required:

LCM of the polynomials

SOLUTION:

Step 1: Factorise each polynomial

Step 2: find the product of each factor that is common in both polynomials.

We have the following,

The common factors would be: =>

(this is common in both polynomials, so we would take just one of them as a factor.

and,

Their product =

m∠a is 90°

m∠b is 40°
