Ответ:

x₁=1 x₂=2.5

Пошаговое объяснение:

$\sqrt{2x-1}>2x-3 \\2x-1>(2x-3)^{2} \\2x-1>4x^{2} -12x+9\\2x-1-4x^{2} +12x-9>0\\-4x^{2} +14x-10>0\\4x^{2} -14x+10>0\\2x^{2} -7x+5>0\\\\D=(-7)^{2}-4*2*5 =49-40=9\\9>0\\D=\sqrt{9}=3\\\\x_{1}=\frac{7-3}{2*2}=\frac{4}{4}=1\\\\ x_{2}=\frac{7+3}{2*2}=\frac{10}{4}=\frac{5}{2}=2.5$
