a: \(\Leftrightarrow2x\left(x+2\right)+4>x^2+4x+4\)
\(\Leftrightarrow2x^2+4x-x^2-4x>0\)
=>x<>0
b: \(\Leftrightarrow3\left(1-2x\right)-24x< 4\left(1-5x\right)\)
=>3-6x-24x<4-20x
=>-30x+3<4-20x
=>-10x<1
hay x>-1/10
c: \(\Leftrightarrow x^2+6x+8>x^2+10x+16+26\)
=>6x+8>10x+42
=>-4x>34
hay x<-17/2

1) \(=\left(9x^2-25y^2\right)-\left(6x-10y\right)=\left(3x-5y\right)\left(3x+5y\right)-2\left(3x-5y\right)=\left(3x-5y\right)\left(3x+5y-2\right)\)
2) \(=9x^2y^2-\left(x^2-2xy+y^2\right)=9x^2y^2-\left(x-y\right)^2=\left(3xy-x+y\right)\left(3xy+x-y\right)\)
