Question

Выполните действие: 2x^2*(4-3x^3) (2a-5c)(a+4c) СРОЧНО

Answer 1

2х^2*(4-3х^3)=8х^2-6х^5 (2а-5с)(а+4с)=2а^2+8ac-5ca-20c^2=2a^2+3ac-20c^2

Answer 2

Calculating the Expression

To calculate the given expression, we will use the following expression:

2x^2*(4-3x^3)+(2a-5c)(a+4c).

Let's break it down step by step.

First, we will simplify the expression 2x^2*(4-3x^3).

The expression 2x^2*(4-3x^3) can be expanded as follows:

2x^2*(4-3x^3) = 8x^2 - 6x^5.

Next, we will simplify the expression (2a-5c)(a+4c).

The expression (2a-5c)(a+4c) can be expanded using the distributive property:

(2a-5c)(a+4c) = 2a^2 + 8ac - 5ac - 20c^2.

Simplifying further, we get:

(2a-5c)(a+4c) = 2a^2 + 3ac - 20c^2.

Now, we will add the two simplified expressions together:

8x^2 - 6x^5 + 2a^2 + 3ac - 20c^2.

This is the simplified form of the given expression.
