Answer:
- 3b(10a - 3b)
Step-by-step explanation:
Given
(5a - 3b)² - 25a² ← this is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
(5a - 3b)² - 25a²
= (5a - 3b)² - (5a)²
= (5a - 3b - 5a)(5a + 3b + 5a) ← simplify parenthesis
= - 3b(10a + 3b)

Answer:
4 1/6
Step-by-step explanation:
Before we can subtract, we have to change the fractions to they have the same denominators. 1/2 becomes 3/6 and 1/3 becomes 2/6. Subtract the converted fractions (3/6-2/6) to get 1/6.
Then, subtract the whole numbers (5-1) to get 4.
Put them together to get 4 1/6.
