Question

-x-4+3x²
please answer​

Answer 1

Step-by-step explanation:

It will be written as

3x² - X - 4

3x² - 4x + 3x - 4 ( splitting the middle term)

3x² + 3x - 4x - 4

(3x² + 3x) (-4x - 4)

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

(X + 1) (3x - 4)

this is the correct answer hope you liked it please mark it as brainliest

Answer 2

Answer:

Step-by-step explanation:

We can write it as 3x²-x+4=0

Now, use the splitting method,

3x²-x+4=0

3x²-4x+3x+4=0

x(3x-4) + 1(3x+4)=0

(x+1)(3x+4)=0

x+1=0                                      3x+4=0

Ans. x=-1                                 3x=-4

                                       Ans. x=-4/3      

HOPE IT HELPS YOU
