Question

factorise m^2+8m+12​

Answer 1

m=-6,-2

I hope tis may help you

Answer 2

$\huge{\textbf{SOLUTION-}}$

m² + 8m + 12

$\mathbb{SUM}$ - 8

$\mathbb{PRODUCT}$ - 12

$\mathbb{PAIRS}$ - 6,2

m² + 6m + 2m + 12

m(m+6) 2(m+6)

(m+2)(m+6)

m = -2

m = -6

This method is known as splitting the middle term method. In this, 2 numbers are taken such that their sum equals the co-efficient of x and their product equals to the constant (the third term). Then, the 2 numbers are written in place of the middle term, then it is factorised
