Question

25 x square - 1 under bracket + 1 + 5 whole square

Answer 1

Step-by-step explanation:

25x(-1)+(1+5)²

=25x (-1) + 26

= -25x+26

Answer 2

$= > 25 {x}^{2} - \frac{1}{ {(1 + 5)}^{2} } \\ \\ = > 25 {x}^{2} - \frac{1}{1 + 25 + 50} \\ \\ = > 25 {x}^{2} - \frac{1}{76}$

$= > \frac{(25 {x}^{2})76 - 1}{76} \\ \\ = > \frac{1976 {x}^{2} }{76} \\ \\ = > 26 {x}^{2}$

Hope you got it
