The polynomial is a difference of perfect squares. use the formula a2 – b2 = (a + b)(a – b) to factor completely. 81x2 – 49 the value of a is . the value of b is . the product of the prime factors is .

(Like pretty much all of my other answers, this is late, but for anyone else that needs it.)

The value of a is 9x

The value of b is 7

The product of the prime factors is (9x-7)(9x+7)

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

sorry can't

i googled though and something came up but it was in science langueage not common english sooo
