Question description

how do I solve with explanation m^2-8m+16/5m^2+m

I must use the following terms to explain my answer:

Domain

Excluded Value

Set

Factor

Real Numbers

Here is an example:

5 – 9w /9w^2-4

9w2  – 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
