Question

(1.1x+2.7y)(1.1x-2.7y)
​

Answer 1

Answer:

(1.1x+2.7y)(1.1x-2.7y)

identity:a(squar)-b(square)=(a+b)(a-b)

(1.1x)square-(2.7y)

1.21x(square)-7.29y(square)

Answer 2

Answer:

1.21x^2-7.29y^2

Step-by-step explanation:

1.1x(1.1x+2.7y)+2.7y(1.1x+2.7y)

1.1x × 1.1x - 1.1x × 2.7y + 2.7y × 1.1x 2.7y × 2.7y

1.21x^2-7.29y^2
