Giải phương trình: \(\left(2^x-8\right)^3+\left(4^x+13\right)^3=\left(4^x+2^x+5\right)^3\)
Giải các PT sau
a)\(\left(3\left(x+1\right)-2\left(x+3\right)\right)^3+\left(2\left(x+3\right)-x+5\right)^3+\left(x-5-3\left(x+1\right)\right)^3=0\)
b)\(\left(x-2\right)^3+\left(x-4\right)^3+\left(x-7\right)^3+3\left(x-2\right)\left(x-4\right)\left(x-7\right)=0\)
giải pt \(x\left(x-1\right)\left(x+1\right)\left(x+2\right)=24\)
\(\left(x+3\right)^4+\left(x+5\right)^4=2\)
\(\frac{x^2+x+4}{2}+\frac{x^2+x+7}{3}=\frac{x^2+x+13}{5}+\frac{x^2+x+16}{6}\)
\(\frac{x+19}{3}+\frac{x+13}{5}=\frac{x+7}{7}+\frac{x+1}{9}\)
giúp vs mình cần gấp
Giải pt
\(\left(x+2\right)\left(x-3\right)+3=\left(x-4\right)\left(x+2\right)-7\)
Giải các pt sau:
a, \(\frac{x+5}{4}-\frac{2x-3}{3}=\frac{6x-1}{8}+\frac{2x-1}{12}\)
b,\(\frac{\left(x+10\right)\left(x+4\right)}{12}-\frac{\left(x+4\right)\left(2-x\right)}{4}=\frac{\left(x+10\right)\left(x-2\right)}{3}\)
Giúp mình với ạ
Giải các pt sau
a,\(\left(x^2+2x+2\right)\left(x^2+2x+3\right)\)=0
b,\(\left(x+3\right)\left(x-3\right)\left(x^2-11\right)+3=2\)
c,\(\left(x+3\right)^4+\left(x+5\right)^4=2\)
Bằng cách phân tích vế trái thành nhân tử, giải các PT sau:
a) \(2x.\left(x-3\right)+5\left(x-3\right)\)
b) \(\left(x^2-4\right)+\left(x-2\right).\left(3-2x\right)=0\)
c) \(x^3-3x^2+3x-1=0\)
Tìm \(x\):

\(9\))\(\left(3x-2\right)\left(x+5\right)=0\)
\(10\))\(\left(x+3\right)\left(x^2+2\right)=0\)
\(11\))\(\left(5x-1\right)\left(x^2-9\right)=0\)
\(12\))\(x\left(x-3\right)+3\left(x-3\right)=0\)
\(13\))\(x\left(x-5\right)-4x+20=0\)
\(14\))\(x^2+4x-5=0\)
Giải PT: \(48x\left(x+1\right)\left(x^3-4\right)=\left(x^4+8x+12\right)^2\)
