Question

1)-2x + x² + 3x² - 4x - 2x² 2)3x-2y'x - 8x'y-3y'5x срочнооо!!!!!​

Answer 1

1) x*(-2+x+3x-4-2x)=2x*(x-3) или можно записать 2x²-6x

2) x*(3-2y-8y-15y)=x*(3-25y)

Answer 2

1) To simplify the expression -2x + x² + 3x² - 4x - 2x², we can combine like terms. Like terms are terms that have the same variable(s) raised to the same power(s). Let's simplify step by step:

-2x + x² + 3x² - 4x - 2x²

First, let's combine the x² terms: x² + 3x² - 2x² = 2x²

Now, let's combine the x terms: -2x - 4x = -6x

Putting it all together, the simplified expression is: 2x² - 6x

2) The expression 3x - 2yx + 8xy - 3y5x can also be simplified by combining like terms. Let's simplify step by step:

3x - 2yx + 8xy - 3y5x

First, let's combine the x terms: 3x - 3y5x = (3 - 3y5)x = (3 - 15y)x = -12yx

Now, let's combine the y terms: -2yx + 8xy = (-2y + 8x)y = (8x - 2y)y = 8xy - 2y²

Putting it all together, the simplified expression is: -12yx + 8xy - 2y²
