7\(\sqrt{4x^2+5x-1}+14\sqrt{x^2-3x+3}=17x-13\)
7 . căn (4x^2 -5x+1) - 14. căn (x^2-3x+3)=17x-13
a) \(\sqrt{3x^2-5x+7}\)+\(\sqrt{3x^2+x+1}\) = 12x-12
b) \(\sqrt{x^2+33}\)+3 = 2x+\(\sqrt{x^2-12}\)
c) 3x-\(8\sqrt{x+14}\) = \(2\sqrt{2x-3}\) - 28
d) \(x^2\)+\(\sqrt{x+7}\) = 7
\(\sqrt{3x^2-7x+3}-\sqrt{x^2-2}=\) = \(\sqrt{3x^2-5x-1}-\sqrt{x^2-3x+4}\)
\(3x^3-17x^2-8x+9+\sqrt{3x-2}-\sqrt{7-x}\) = 0
