Question

1) 4x²-4x+1
2) 8x²-21x+10
FACTORISE THIS BOTH.

Answer 1

Answer:

$(i) \: \: 4 {x}^{2} - 4x + 1 = 0 \\ \\ 4 {x}^{2} - 2x - 2x + 1 = 0 \\ \\ {(2x - 1)}^{2} = 0 \\ \\ (ii)8 {x}^{2} - 21x + 10 = 0 \\ \\ 8 {x}^{2} - 16x - 5x + 10 = 0 \\ \\ 8x(x - 2) - 5(x - 2) = 0 \\ \\ (8x - 5)(x - 2) = 0$

Answer 2

Answer:

4x^2-2x-2x+1

2x(2x_1)x(2+1)
