Find the value of x such that: \(\frac{3\left(x+2\right)}{2x+3}=\frac{7}{8},\left(x\ne-\frac{3}{2}\right)\) . Answer: x = ...
( write your answer by decimal in simplest form )
1. Find the positive value of x such that:
\(x^2-2-2x-2\left|x-1\right|=0\)
2. Find the remainder of the division:
\(\left(x^3-13+5x-3x^2\right):\left(x-3\right)\)
Câu 1:
\(\Leftrightarrow x^2-2x+1-2\left|x-1\right|-3=0\)
\(\Leftrightarrow\left(\left|x-1\right|\right)^2-2\left| x-1\right|-3=0\)
\(\Leftrightarrow\left(\left|x-1\right|-3\right)\left(\left|x-1\right|+1\right)=0\)
=>x-1=3 hoặc x-1=-3
=>x=4 hoặc x=-2
