Question

50x2-2(x-2)2factorise​

Answer 1

Answer:

(2x + 1)(24x - 8) or 8(2x + 1)(3x - 1)

Step-by-step explanation:

50x2 - 2(x2 + 4 -4x)

50x2 - 2x2 - 8 + 8x

48x2 + 8x - 8

8(6x2 + x - 1)

8(6x2 + 3x - 2x - 1)

8(3x(2x + 1) - 1(2x + 1))

24x(2x + 1) - 8(2x + 1)

(2x + 1)(24x - 8) or 8(2x + 1)(3x - 1)
