Question

12x square + 21x -6 =0 (factorisation method)
​

Answer 1

Answer:

1/4 and -2

Step-by-step explanation:

12x² + 21 x - 6 =0

3(4x² + 7x - 2) =0

(4x² + 7x - 2) = 0/3

4x² + 7x - 2 = 0

4x² + 8x - x - 2 = 0

4x(x + 2) -1(x + 2) =0

(4x-1)(x + 2) = 0

Thus, 4x-1=0

         4x = 1

          x = 1/4

and x + 2 =0

       x = -2

Hope it helps
