Question

А) 3(y+5)²=0 тут y должен быть -5, но я не знаю как его получитьпомогитеб) (3y+5)²=9y²а тут у будет -5/6

Answer 1

А) Решение

3(у+5)²=0

(у+5)²=0

у+5=0

Ответ у=-5

Б) Решение

(3у+5)²=9у²

9у²+30у+25=9у²

30у+25=0

30у=-25

Ответ

у=-5/6

Answer 2

a) To solve the equation 3(y+5)²=0, you can start by dividing both sides of the equation by 3:

(y+5)² = 0

Next, take the square root of both sides of the equation:

y+5 = 0

Subtract 5 from both sides to isolate y:

y = -5

Therefore, the solution to the equation 3(y+5)²=0 is y=-5.

b) To solve the equation (3y+5)²=9y², you can start by expanding the left side of the equation:

9y² + 30y + 25 = 9y²

Subtract 9y² from both sides of the equation:

30y + 25 = 0

Subtract 25 from both sides of the equation:

30y = -25

Divide both sides of the equation by 30:

y = -5/6

Therefore, the solution to the equation (3y+5)²=9y² is y=-5/6.
