Question

Factorize: 3x2-X-4 ​

Answer 1

Answer:

(3x-4) (x+1)

solution :

3x^2 + 3x - 4x - 4

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

(3x-4) (x + 1)

Answer 2

Answer:

x = 4/3 and, -1

Step-by-step explanation:

3x² - x - 4

=3x² - 4x + 3x - 4

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

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

Therefore,

3x-4=0

3x=4

x=4/3(Ans)

And,

x+1=0

x = -1(Ans)
