how do I solve with explanation m^2-8m+16/5m^2+mI must use the following terms to explain my answer:DomainExcluded ValueSetFactorReal NumbersHere is an example:5 – 9w /9w^2-49w2  – 4 = 0 I notice this is a difference of squares which I can factor. (3w – 2)(3w + 2) = 0 Set each factor equal to zero. 3w – 2 = 0 or 3w + 2 = 0 Add or subtract 2 from both sides. 3w = 2 or 3w = -2 Divide both sides by 3. w = 2/3 or w = -2/3 These are the excluded values for my second expression
