Question

(8x²-9y²) factorise the following

Answer 1

Answer:

It is (2\sqrt2

2

x - 3y)(2\sqrt2

2

x - 3y)

Step-by-step explanation

Answer 2

Answer:

(2√2 X -3y) (2√2x +3y)

Step-by-step explanation:

8x^2 - 9y^2

Factorising completely, we get

1. for 8x^2 = 2√2x

2. for 9y^2 = 3y

hence the factorisation can be completed as;

(2√2x-3y)(2√2x+3y)
