Question

Find product of (6x-8y)(6x+8y) is ______.
a. 36x-64y
b. 36x^2+96xy+64^2
c. 36x^2-64y^2
d. 36x^2-96xy-64y^2​

Answer 1

Answer:

option c

Step-by-step explanation:

6x * 6x = 36x^2

6x * 8y = 48xy

-8y * 6x = -48xy

-8y * 8y = -64y^2

36x^2- 64y^2

Answer 2

Answer:

(a-b)(a+b)

=a^2 - b^2

= (6x)^2 - (8y)^2

=36x^2 -64y^2
