Answer 4

a, \(x^2\left(2x+3\right)+\left(2x+3\right)=\left(x^2+1\right)\left(2x+3\right)\)

b, \(x^2z\left(x-z\right)+xyz\left(x-z\right)=\left(x^2z+xyz\right)\left(x-z\right)=xz\left(x+y\right)\left(x-z\right)\)

c, \(8y^2\left(xy-3\right)-5z\left(xy-3\right)=\left(8y^2-5z\right)\left(xy-3\right)\)

e,\(\left(x-4\right)\left(x-2\right)\)

g, \(\left(x-4\right)\left(x+3\right)\)
