What is the factorization of 49b2 − 81?

Step-by-step explanation:

49b² - 81 = (7b)² - 9 ²

by identity : 49b² - 81 = (7b -  9)( 7b + 9)

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

it has the same slope and a different y-intercept

hope this : )
