Question

1. (4b-5bc+4)-(9b+10bc)2. 7х²(2х²+2)помогите пж​

Answer 1

Ответ:

1) -5b - 15bc + 4

2)14x⁴ + 14x²

Объяснение:

1)(4b - 5bc + 4)-(9b+10bc)=4b - 5bc + 4 -9b - 10bc =  -5b - 15bc + 4

2)7x²(2x² + 2) = 7x² * 2x² + 7x² * 2  = 14x⁴ + 14x²

Answer 2

1. 4b-5bc+4-9b-10bc=-5b-15bc+4

Answer 3

Simplifying Algebraic Expressions

To simplify the given algebraic expressions, let's start with each expression separately.

1. Simplify (4b - 5bc + 4) - (9b + 10bc):

To simplify this expression, we'll first distribute the negative sign inside the parentheses and then combine like terms.

The expression becomes: ``` 4b - 5bc + 4 - 9b - 10bc ```

Now, let's combine like terms: ``` (4b - 9b) + (-5bc - 10bc) + 4 ```

Simplifying further: ``` -5b - 15bc + 4 ```

So, the simplified expression is -5b - 15bc + 4.

2. Simplify 7x²(2x² + 2):

To simplify this expression, we'll use the distributive property to multiply 7x² by each term inside the parentheses.

The expression becomes: ``` 7x² * 2x² + 7x² * 2 ```

Multiplying each term: ``` 14x^4 + 14x² ```

So, the simplified expression is 14x^4 + 14x².

Therefore, the simplified expressions are: 1. -5b - 15bc + 4 2. 14x^4 + 14x²
