Part B: The area of a rectangle is (9a² - 25b²) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work​

Answer 1

A:

16a^2-24a+9

16a^2-12a-12a+9

4a(4a-3)-3(4a-3)

(4a-3)(4a-3)

(4a-3)^2

(4a-3)^2

B: Use difference of squares method

(3a+5b)(3a−5b)
