Question

How to factorise 4s^2-4s+1?​

Answer 1

Answer:

hope it will help

Step-by-step explanation:

4s²-4s+1

4s²-2s-2s+1

2s(2s-1) - 1(2s-1)

(2s-1) (2s-1)

Answer 2

hello mate,

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

1st zero

$2s - 1 = 0 \\ \\ 2s = 1 \\ \\ s = \frac{1}{2}$

second zero

$2s - 1 = 0 \\ \\ 2s = 1 \\ \\ s = \frac{1}{2}$

hope it will help you
