Question 1137285

the dimensions of a rectangle that has an area of {{{m^2 - mv-56v^2}}}:



{{{m^2 - mv-56v^2}}}.........factor completely

{{{m^2 - mv-56v^2}}}....write {{{-mv}}} as {{{-8mv+7mv}}}

{{{m^2 - 8mv+7mv-56v^2}}}............group

{{{(m^2 - 8mv)+(7mv-56v^2)}}}

{{{m(m - 8v)+7v(m-8v)}}}

{{{(m + 7v) (m - 8 v)}}}

=>{{{(m + 7v)}}} and {{{(m - 8 v)}}} are dimensions of a rectangle
