Hello :)
First, find the common factor of all of the terms.
4 ⋅ 2 = 8
x ⋅ x ⋅ x = [tex]x^{3}[/tex]
4 ⋅ 7 = 28
x ⋅ x= [tex]x^{2}[/tex]
4 ⋅ 10 = 40
x = x
the common factor of all of the terms is 4x.
Next, divide the original equation by 4x.
4x([tex]8x^{3} +28x^{2}+40x[/tex])
[tex]\frac{8x^{2} }{4x}+\frac{28x^2}{4x}+\frac{40x}{4x}[/tex]
[tex]4x(2x^2+7x+10)[/tex]
