Question

Foctonise : 4x²-x-3​

Answer 1

Step-by-step explanation:

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

Answer 2

Answer:

x = -1 or x = -3/4

Step-by-step explanation:

4x²-x-3

4x²-4x+3x-3

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

(x-1) (4x-3)

x-1 = 0

x = 1

or

4x+3 = 0

4x = -3

x = -3/4
