14а2=0

а=0

Answer 2

To solve the equation 10a(4a+6)-(26a^2-16a)-76a=0, follow these steps:

1. Distribute the terms within parentheses: 40a^2 + 60a - (26a^2 - 16a) - 76a = 0

2. Remove the parentheses and simplify the equation: 40a^2 + 60a - 26a^2 + 16a - 76a = 0

3. Combine like terms: (40a^2 - 26a^2) + (60a + 16a - 76a) = 0 14a^2 + (60a + 16a - 76a) = 0

4. Combine the like terms within the parentheses: 14a^2 - 76a = 0

5. Factor out the common factor (2a): 2a(7a - 38) = 0

6. Now, set each factor equal to zero and solve for 'a': 2a = 0 => a = 0 7a - 38 = 0 => 7a = 38 a = 38/7

So, the solutions to the equation are: a = 0 a = 38/7
