Question

Choose the correct product of (5x − 11)^2.
a. 25x^2 − 110x + 121
b. 25x^2 − 121
c. 25x^2 + 121
d. 25x^2 + 110x + 121

Answer 1

Answer:

A. 25x^2 - 110x + 121

Step-by-step explanation:

Answer 2

(5x - 11)² = (5x)² - 2·5x·11 + (11)² = 25x² - 110x + 121

(a - b)² = a² - 2ab + b²

a. 25x² − 110x + 121
