Question

The product of (6xy-5)(6xy+5)​

Answer 1

`\bf36x^2y^2-25`

Explanation:

`\boxed{\displaystyle\\(a-b)(a+b)=a^2-b^2}\\\\(6xy-5)(6xy+5)=(6xy)^2-5^2=36x^2y^2-25`

Answer 2

Answer: 36x^2y^2 - 25

Explanation:

(6xy-5)(6xy+5)​=

(6xy*6xy)+(6xy*5)+(6xy*(-5))+(-5*5)=

36x^2y^2 + 30xy + (-30xy) + (-25)=

36x^2y^2 + (-25)=36x^2y^2 - 25
