 Question 83584: Find a value for k so that 9m squared-kn squared will have the factors 3m+7n and 3m-7n Help please, and show step by step. Thank YouAnswer by stanbon(60771)   (Show Source): You can put this solution on YOUR website!Find a value for k so that 9m squared-kn squared will have the factors 3m+7n and 3m-7n ------------------- 9m^2-kn = (3m+7n)(3m-7n) 9m^2-kn = 9m^2-49n^2 -kn = -49n^2 k= (-49n^2)/(-n) k = 49n ============= Cheers, Stan H.
