Question

Factorize 21x2 - 2x + 1/21​

Answer 1

Step-by-step explanation:

$21 {x}^{2} - 2x + \frac{1}{21} = > 21 {x}^{2} - x - x +$

$\frac{1}{21} = > x(21x - 1) - \frac{1}{21}(21x - 1) = >$

$= > (21x - 1)(x - \frac{1}{21}) = >$

$(21x - 1) \frac{(21x - 1)}{21} = > \frac{ {(21x - 1)}^{2} }{21}$

Hope it helps you.
