Question

Find the factors of 3 x2 - X - 4​

Answer 1

Answer:

Given polynomial :-

3x2 - x -4

From the given polynomial ,

3x2 - x -4

sum = middle term = - 1

product = 3 × -4 = -12

[ - 4 ,3 ]

3x2 - x - 4 =0

3x2 +3x -4x -4 =0

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

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

x+1 = 0 [or ] 3x - 4 =0

=> [x = - 1 & x = 4/3]
