1, \(12x^2+7x-12=12x^2+16x-9x-12=\left(3x+4\right)\left(4x-3\right)\)
2, \(2m^2+10m+8=2m^2+2m+8m+8=\left(2m+8\right)\left(m+1\right)\)
\(12x^2+7x-12=12x^2-9x+16x-12\)
\(=3x\left(4x-3\right)+4\left(4x-3\right)=\left(3x+4\right)\left(4x-3\right)\)
\(2m^2+10m+8=2m^2+2m+8m+8\)
\(=2m\left(m+1\right)+8\left(m+1\right)=2\left(m+4\right)\left(m+1\right)\)
\(1.12x^2+7x-12=\left(4x-3\right)\left(3x+4\right)\\ 2.2m^2+10m+8=2\left(m+1\right)\left(m+4\right)\)
1: \(12x^2+7x-12\)
\(=12x^2+16x-9x-12\)
\(=4x\left(3x+4\right)-3\left(3x+4\right)\)
\(=\left(3x+4\right)\left(4x-3\right)\)
