Question

(5x²x-2)(7x²-5x)=пожалуйста​

Answer 1

Ответ:

$35x {}^{4} - 25x {}^{3} - 14x {}^{2} + 10x$

Answer 2

To expand and simplify the expression (5x²x-2)(7x²-5x), we can use the distributive property of multiplication over addition. This property states that for any three numbers a, b, and c, the product of a and the sum of b and c is equal to the sum of the products of a and b and a and c.

Let's break down the expression step by step:

(5x²x-2)(7x²-5x)

First, we can simplify the expression 5x²x to 5x³ by combining the exponents of x:

(5x³-2)(7x²-5x)

Next, we can apply the distributive property by multiplying each term in the first parentheses by each term in the second parentheses:

(5x³ * 7x²) + (5x³ * -5x) + (-2 * 7x²) + (-2 * -5x)

Simplifying further, we have:

35x^(3+2) - 25x^(3+1) - 14x² + 10x

Now, we can combine the like terms:

35x^5 - 25x^4 - 14x² + 10x

So, the expanded and simplified expression is 35x^5 - 25x^4 - 14x² + 10x.
