<=> \(\frac{4x-15}{5}=\frac{x\left(4x-15\right)}{5}\)
<=> 4x - 15 = x (4x-15)
<=> x = 1
<=> \(\frac{4x-15}{5}=\frac{x\left(4x-15\right)}{5}\)
<=> 4x - 15 = x (4x-15)
<=> x = 1

a,\(\frac{4}{5}x-3=\frac{1}{5}x\left(4x-15\right)\)
b,(x-3)-\(\frac{\left(x-3\right)\left(2x-5\right)}{6}=\frac{\left(x-3\right)\left(3-x\right)}{4}\)
c,\(\frac{\left(3x+1\right)\left(3x-2\right)}{3}+5\left(3x+1\right)=\) \(\frac{2\left(2x+1\right)\left(3x+1\right)}{3}+2x\left(3x+1\right)\)

1,\(\frac{2x+5}{6}-\frac{\left(2x+5\right)\left(x-10\right)}{3}=0\)
2,(4x-1)(x-5)=\(x^2\)-25
3,\(x^3-6x^2=x^2-3x\)
4,x\(\left(x+3\right)^3-\frac{x}{4}\left(x+3\right)\)=0
Bài 1: Giải các phương trình sau:
a. (x - 1)2 (3x - 1)= 0
b.\(\left(\frac{2x}{3}+4\right)\left(2x-3\right)\left(\frac{x}{2}-1\right)=0\)
c.\(\left(x^2-4\right)\left(\frac{x}{4}-\frac{4x+5}{3}\right)=0\)
giải phương trình
\(\frac{5-x}{4x^2-8x}+\frac{7}{8}=\frac{x-1}{2x\left(x-2\right)}+\frac{1}{8x-16}\)
\(x^3+x^2+4=0\)
\(\left(x-\frac{3}{4}\right)^2+\left(x-\frac{3}{4}\right)\left(x-\frac{1}{2}\right)=0\)
\(\left(4x-\frac{4x-3}{5}-\frac{2\left(x+3\right)}{7}\right)=0\)
