\(=\left(\frac{84}{13}+\frac{35}{13}\right)^2-2\cdot\frac{84}{13}\cdot\frac{35}{13}\) 

\(=7^2-\frac{5880}{169}\)   

\(=49-\frac{5880}{169}\) 

\(=\frac{8281}{169}-\frac{5880}{169}=\frac{2401}{169}\)

\(7^{2x-3}-2.49=49.5\)

\(7^{2x-3}-2.49=245\)

\(7^{2x-3}-2=245:49\)

\(7^{2x-3}-2=5\)

\(7^{2x-3}=5+2\)

\(7^{2x-3}=7\)

2x-3=1

2x=1+3

2x=4

x=4:2

x=2

vậy x=2
