7.) Explain WHY the answer below is incorrect for 16m = 4m +3 3-4m 16m ²-9 3-4m You would factor this expression using a^2-b^2=(a+b)(a-b). You should have (4m+3)(4m-3)/(4m-3). Factor out the -1 and cross out the common factor. Based on the answer above it looks like it may have been solved like this, (4m-31(4m+3)/(4m-3). The answer is incorrect because.......
