Question

3x^2-x-4,factorise by spilling method​

Answer 1

Answer:

Here's your answer

$3 {x}^{2} - x - 4 \\ \\ 3 {x}^{2} - 4x + 3x - 4 \\ \\ x(3x - 4) + 1(3x - 4) \\ \\ (3x - 4)(x + 1)$

Hope it helps ✌...

Answer 2

3x² - x - 4

__________ [ GIVEN ]

• We have to factorise it by splitting method

_____________________________

=> 3x² - x - 4

The above equation is in the form ax² - bx + c

Here the middle term is b = -x. We have to split it like that it's sum came 'b' and product came 'c'.

=> 3x² - (- 3x + 4x) - 4

=> 3x² + 3x - 4x - 4

=> 3x(x + 1) - 4(x + 1)

=> (x + 1) (3x - 4)

____________________________

(x + 1) (3x - 4) are the factors came by splitting the 3x² - x - 4.
