Answer:
[tex]\boxed{\bold{4x^2\left(6xy^2-y+21x^2\right)}}[/tex]
Step By Step Explanation:
Apply Exponent Rule [tex]\bold{\:a^{b+c}=a^ba^c}[/tex]
[tex]\bold{x^4=x^2x^2,\:x^3y^2=x^2x}[/tex]
[tex]\bold{24x^2x-4x^2y+84x^2x^2}[/tex]
Rewrite 84: [tex]\bold{21\cdot \:4}[/tex]
Rewrite 24: [tex]\bold{6\cdot \:4}[/tex]
[tex]\bold{6\cdot \:4x^2x-4x^2y+21\cdot \:4x^2x^2}[/tex]
Factor Out Common Term [tex]\bold{4x^2}[/tex]
[tex]\bold{4x^2\left(6xy^2-y+21x^2\right)}[/tex]
➤ [tex]\boxed{\bold{Mordancy}}[/tex]
