Answer:
The answer is (4x - 5)(4x + 5)
Step-by-step explanation:
∵ f(x) = 16x² - 25 ⇒ it is a difference of two squares
∴ It factored into two bracket like each other with different middle sign because there is no middle term
∴ 16x² - 25 = (4x - 5)(4x + 5)
To check:
(4x - 5)(4x + 5) = 16x² + 20x - 20x - 25
= 16x² - 25
Answer:
(4x-5)(4x+5)
Step-by-step explanation:
We have given the expression.
16x²-25
We have to find the factors of given expression.
Using difference formula which is:
a²-b² = (a-b)(a+b)
16x²-25 = (4x)²-(5)²
a = 4x and b = 5
Putting values in formula, we have
16x²-25 = (4x-5)(4x+5) which is the answer.
