the dimensions of a rectangle that has an area of m%5E2+-+mv-56v%5E2:


m%5E2+-+mv-56v%5E2.........factor completely
m%5E2+-+mv-56v%5E2....write -mv as -8mv%2B7mv
m%5E2+-+8mv%2B7mv-56v%5E2............group
%28m%5E2+-+8mv%29%2B%287mv-56v%5E2%29
m%28m+-+8v%29%2B7v%28m-8v%29
%28m+%2B+7v%29+%28m+-+8+v%29
=>%28m+%2B+7v%29 and %28m+-+8+v%29 are dimensions of a rectangle
