Question 407313


{{{75x^4+35x^3-10x^2}}}......common divisor is {{{5}}}

{{{75x^4/5+35x^3/5-10x^2/5}}}

{{{15x^4+7x^3-2x^2}}}.........common {{{x^2}}}

{{{x^2(15x^2+7x-2)}}}........write {{{7x}}} as {{{10x-3x}}}

{{{x^2(15x^2+10x-3x-2)}}}....group

{{{x^2((15x^2+10x)-(3x+2))}}}

{{{x^2(5x(3x+2)-(3x+2))}}}

{{{x^2(5x-1)(3x+2)}}}
