Question

3x^2-x-4 factorise and answer

Answer 1

Step-by-step explanation:

3x2 - x - 4 = 0

By splitting the middle term,

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

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

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

x+1 = 0. 3x - 4 = 0

x = -1. x = 4/3

Answer 2

Answer:

3x^2-x-4 = 0

3x^2-4x+3x-4 =0

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

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

x=4/3 or x=-1
