Question

11a-0.5а^2=2.5a^2-25a хеелп

Answer 1

11a-0.5a(2)
а=22
2.5а(2)-25а
а=10
если а подставить в каждое свое выражения получится ноль! 

Answer 2

To solve the equation 11a - 0.5a^2 = 2.5a^2 - 25a, we can follow these steps:

1. Combine like terms on both sides of the equation: -0.5a^2 - 2.5a^2 + 11a + 25a = 0

2. Simplify the equation: -3a^2 + 36a = 0

3. Factor out 'a' from the equation: a(-3a + 36) = 0

4. Set each factor equal to zero and solve for 'a': a = 0 or -3a + 36 = 0

5. Solve the second equation: -3a + 36 = 0 -3a = -36 a = -36 / -3 a = 12

Therefore, the solutions to the equation are: a = 0 and a = 12.
