Answer:
(4a - 11b)(4a + 11b)
Step-by-step explanation:
16a² - 121b² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
16a² - 121b²
= (4a)² - (11b)²
= (4a - 11b)(4a + 11b)
Answer:
Step-by-step explanation:
Rule: (a^2-b^2)=(a-b)(a+b) (‘difference of squares’)
16a^2-121b^2
(4a-11b)(4a+11b)
