Question

3x^2-x-4 how to split the middle term

Answer 1

(3x^2 +3x )- ( 4x - 4 )
3x ( x +1) - 4 ( x + 1 )
( 3x - 4 ) ( x -1 )

alpha =4/3    &      bita = -1

Answer 2

Solution :-

⇒ 3x² - x - 4

By splitting middle term

⇒ 3x² - 4x + 3x - 4

⇒ x ( 3x - 4 ) + 1 ( 3x - 4 )

⇒ ( x + 1 ) ( 3x - 4 )
