Question

Despejar la x:
1. (x - 3)2 = 25
2. (2 x - 3)2 = 49

Answer 1

1. (x-3)2=25

x-3=25/2

x=25/2+3

2. (2x-3)2=49

(2x-3)=49/2

2x=49/2+3

x=(49/2+3)/2

Answer 2

$x - 3 = \frac{25}{2} \\ x = \frac{25}{2} + 3$
.......
$2x - 3 = \frac{49}{2} \\ 2x = \frac{49}{2} + 3 \\ 2x = \frac{49 + 6}{2} \\ x = \frac{55}{2 \times 2} \\ x = \frac{55}{4}$
