Answer 2

Hello...
Answer....

Solution :
We have,
$25x = {536}^{2} - {136}^{2} \\ \\ = > {25x}^{2} = (536 + 136) \times (536 - 136) \: \: \: \: \: {using \: {a}^{2} - {b}^{2} = (a + b)(a - b)} \\ \\ = > 25x = 672 \times 400 \\ \\ = > \frac{25x}{25} = \frac{672 \times 400}{25} \: \: \:{ dividing \: both \: sides \: by \: 25} \\ \\ = > x = 672 \times 16 \\ \\ = > x = 10752$
Hope it helped
