Answer 1

Ответ:

$(5y {}^{2} + 8y - 8) - (4y {}^{2}3y + 11) \\ 5y {}^{2} + 8y - 8 - 4y {}^{2} + 3y - 11 \\ y {}^{2} + 11y - 19 \\ - - - - - - - - - - - - - \\ - 4x(3x - x {}^{3} + 7) \\ - 12x {}^{2} + 4x {}^{4} - 28x \\ 4x {}^{4} - 12x {}^{2} - 28x$

Answer 2

To simplify the given expression:

(5y² + 8y - 8) - (4y² + 11) - 4x(3x - x³ + 7)

First, let's simplify each part separately:

1. Simplify (5y² + 8y - 8) - (4y² + 11):

   (5y² + 8y - 8) - (4y² + 11) = 5y² + 8y - 8 - 4y² - 11

   Now, combine like terms (5y² - 4y²) and (-8 - 11):

   y² + 8y - 19

2. Now, let's simplify 4x(3x - x³ + 7):

   4x(3x - x³ + 7) = 4x * 3x - 4x * x³ + 4x * 7

   Now, multiply each term inside the parentheses by 4x:

   12x² - 4x⁴ + 28x

Now, we can rewrite the original expression with these simplified parts:

(y² + 8y - 19) - (12x² - 4x⁴ + 28x)

Now, you can leave it in this simplified form or rearrange the terms if needed.
