20 БАЛЛОВ! ПОЖАЛУЙСТА ПОМОГИТЕ! ЗАДАНИЕ ВРОДЕ БЫ НЕ СЛОЖНОЕ Разложить на множители:25в^2-16Решите уравнение:4у^2-25=0

Answer 1

(5в-4)(5в+4)

4у^2-25=0
4у^2=25
4у=5
у=5/4
у=1,25

Answer 2

Hey there! It sounds like you need some help with math. I'd be happy to assist you! For the first question, we need to factor 25v^2 - 16. This is a difference of squares pattern, so we can write it as (5v)^2 - 4^2 and factor it as (5v - 4)(5v + 4). For the second question, we can start by adding 25 to both sides to get 4y^2 = 25. Then we can take the square root of both sides to get 2y = ±5. Solving for y, we get y = ±(5/2).
