Answer 1

Раскрываем скобки потом взимо уничтожаем x³+3x у нас осталось +1 и -9 получаеться -8

Answer 2

Solution to Equation (a):

To solve the equation 3у + 2/4у* + у + у - 3/16у*-1 = 3/4у - 1, we will follow these steps:

Step 1: Simplify the equation by combining like terms and getting rid of any parentheses or brackets.

Step 2: Isolate the variable 'у' on one side of the equation.

Step 3: Solve for 'у' by performing the necessary operations.

Let's solve the equation step by step:

Step 1: Simplify the equation - Combine like terms on both sides of the equation: - On the left side, we have 3у + 2/4у* + у + у - 3/16у*-1. - On the right side, we have 3/4у - 1.

Step 2: Isolate the variable 'у' - Move all terms containing 'у' to the left side of the equation and all constant terms to the right side: - The equation becomes 3у + 2/4у* + у + у - 3/16у*-1 - 3/4у = -1.

Step 3: Solve for 'у' - Combine like terms on the left side of the equation: - The equation becomes 5у + 2/4у* - 3/16у*-1 = -1. - Simplify the equation further: - The equation becomes 5у + 1/2у - 3/16у*-1 = -1. - Multiply both sides of the equation by the least common denominator (LCD) to eliminate the fractions: - The equation becomes 80у + 8у - 3у = -16. - Combine like terms on the left side of the equation: - The equation becomes 85у - 3у = -16. - Simplify the equation further: - The equation becomes 82у = -16. - Divide both sides of the equation by 82 to solve for 'у': - The solution is у = -16/82.

Therefore, the solution to equation (a) is у = -8/41.

Solution to Equation (b):

To solve the equation (х* + 3х + 1) + (х* + 3х - 9), we will follow these steps:

Step 1: Simplify the equation by combining like terms and getting rid of any parentheses or brackets.

Step 2: Combine like terms further if possible.

Let's solve the equation step by step:

Step 1: Simplify the equation - Combine like terms within each set of parentheses: - The equation becomes х* + 3х + 1 + х* + 3х - 9.

Step 2: Combine like terms further - Combine like terms on both sides of the equation: - The equation becomes 2х* + 6х - 8.

Therefore, the simplified form of the equation is 2х* + 6х - 8.

I hope this helps! Let me know if you have any further questions.
