Question

13. Factorise :
5. x2 - 4x - 12
chapter 14 . Factorisation​

Answer 1

Answer:

Use the sum-product pattern

52−4−12

52+6−10−12

2

Common factor from the two pairs

52+6−10−12

(5+6)−2(5+6)

3

Rewrite in factored form

(5+6)−2(5+6)

(−2)(5+6)

Solution

(−2)(5+6)

Answer 2

$\mathbb { SOLUTION:- }$

$\longrightarrow { {x}^{2} - 4x - 12 }$

$\longrightarrow { {x}^{2} + 2x - 6x - 12 }$

$\longrightarrow {x(x + 2) - 6(x + 2)}$

$\longrightarrow (x + 2)(x - 6)$

Hope this helps you.
