Question

x ^ 2 + 12x + 24 factorise the following expression​

Answer 1

Step-by-step explanation:

The first term is, x2 its coefficient is 1 .

The middle term is, -12x its coefficient is -12 .

The last term, "the constant", is +24

Step-1 : Multiply the coefficient of the first term by the constant 1 • 24 = 24

Step-2 : Find two factors of 24 whose sum equals the coefficient of the middle term, which is -12 .

-24 + -1 = -25

-12 + -2 = -14

-8 + -3 = -11

-6 + -4 = -10

-4 + -6 = -10

-3 + -8 = -11

-2 + -12 = -14

-1 + -24 = -25

1 + 24 = 25

2 + 12 = 14

3 + 8 = 11

4 + 6 = 10

6 + 4 = 10

8 + 3 = 11

12 + 2 = 14

24 + 1 = 25

Observation : No two such factors can be found !!
