Factorise x^(2)+5x+6
To factorise we must think what two numbers add up to 5 but times together to get 6. We know it is two numbers because it is x^(2). If it was x^(3) there could be 3 numbers, ect. We think what goes into 6: (6, 1) and (3, 2) (3,2) add up to 5! Therefor the answer is:(x+3)(x+2) We can check this by multiplying out the brackets.
