"True: the product of two polynomials will be a polynomial regardless of the signs of the leading coefficients of the polynomials. When two polynomials are multiplied, each term of the first polynomial is multiplied by each term of the second polynomial."
The ratio of phelps to mabry is 3:2, meaning for every 5 records, phelps approved 3 and mabry 2. So:

Answer:
(3x - 7y)(3x + 7y)
Step-by-step explanation:
9x² - 49y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
here 9x² = (3x)² ⇒ a = 3x and 49y² = (7y) ⇒ b = 7y
9x² - 49y²
= (3x)² - (7y)² = (3x - 7y)(3x + 7y)
