Two positive integers are 3 units apart on a number line. Their product is 108.

Which equation can be used to solve for m, the greater integer?

m(m – 3) = 108

m(m + 3) = 108

(m + 3)(m – 3) = 108

(m – 12)(m – 9) = 108

Question

Two positive integers are 3 units apart on a number line. Their product is 108.

Which equation can be used to solve for m, the greater integer?


m(m – 3) = 108  

m(m + 3) = 108

(m + 3)(m – 3) = 108

(m – 12)(m – 9) = 108

take equation and solve for m

raffle_snaffle · Answer

take each equation and solve for me. We need to find what m makes the equation a solution.

Using what @raffle_snaffle said 

     >> "take each equation and solve for me. We need to find what m makes the equation a solution.”

I just want to add to that..

All you basically have to do is solve for $m$ in each equation and find out which equation can be used to solve for $m$, the greatest integer as your question states.
