Question

factorise : x² - 4x -12 ( by split the middle term)​

Answer 1

$\LARGE{\underline{\sf{\red{Answєr :}}}}$

x² - 4x -12

━━━━━━━━━━━━━━━━━━━━━━━━━━

Sum = - 4

Product = - 12

So ,

2 × 6 = 12

3 × 4 = 12

Hєncє ,

2 × - 6 = - 12

2 + (- 6) = - 4

━━━━━━━━━━━━━━━━━━━━━━━━━━

x² + 2x - 6x - 12

x.x + 2.x - 2.3.x - 2.2.3

( Tαkє thє common fαctors out )

x [ x + 2 ] - 6 [ x + 2 ]

= $\LARGE{\boxed{\sf{\red{[ x + 2 ] [ x - 6 ]}}}}$
