Answer 1

Step-by-step explanation:

tex] \begin{lgathered}\tt \implies \: (25 - x) {}^{2} = (x) {}^{2} + (5) {}^{2} \\ \tt \implies625 - 50 + x {}^{2} = x {}^{2} + 25 \\ \tt \implies - 50xtex] \begin{lgathered}\tt \implies \: (25 - x) {}^{2} = (x) {}^{2} + (5) {}^{2} \\ \tt \implies625 - 50 + x {}^{2} = x {}^{2} + 25 \\ \tt \implies - 50x
