Question

pls someone answer to this question​

Answer 1

Answer:

Step-by-step explanation:

• 81x^2 + 9y^2 - 54xy / -9^y2 + 81x^2

• 81x^2 + 9y^2 - 54xy / 81x^2 - 9y^2

• (9x - 3y)^2 / (9x)^2 -(3y)^2                 {a^2 + b^2 -  2ab = (a-b)^2}

• (9x - 3y)^2 / (9x+3y)(9x-3y)             {(a^2  - b^2 = (a+b)(a-b)}

• (9x - 3y) (9x - 3y) / (9x + 3y) (9x - 3y)

cancel out the common (9x - 3y)

• (9x - 3y) / (9x + 3y)

taking out common( 3 )

• 3(3x - y) / 3(3x + y)

cut 3

• (3x - y) / (3x + y)
