Which expression is equivalent to 121x^2 - 64y^2?
a. (11x - 16y) (11x + 16y)
b. (11x - 16y) (11x - 16y)
c. (11x + 8y) (11x + 8y)
d. (11x + 8y) (11x - 8y)

D is the correct answer

Step-by-step explanation:

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
