Consider the polynomials

a)${x}^{2}-8x$

b)${x}^{3}+3{x}^{2}-18x$

c)${x}^{3}-10x$

a)${x}^{2}-8x$

${x}^{2}-8x=x(x-8)$

b)${x}^{3}+3{x}^{2}-18x$

${x}^{3}+3{x}^{2}-18x=x({x}^{2}+3x-18)$

$=x({x}^{2}+6x-3x-18)$

$=x(x(x+6)-3(x+6))$

$=x(x+6)(x-3)$

${x}^{3}+3{x}^{2}-18x=x(x+6)(x-3)$

c)${x}^{3}-10x$

${x}^{3}-10x=x({x}^{2}-10)$
