Answer 2

Calculation of the Expression

To find the sum, difference, and product of the expression 2x^2 + 5x - 1 + 3x^2 + 5x - 3, we need to combine like terms and perform the necessary operations.

Let's start by combining the like terms:

2x^2 + 3x^2 = 5x^2 5x + 5x = 10x -1 - 3 = -4

Now, we have the simplified expression: 5x^2 + 10x - 4.

Sum

The sum of the expression 2x^2 + 5x - 1 + 3x^2 + 5x - 3 is the result when all the terms are added together. In this case, the sum is:

(2x^2 + 5x - 1) + (3x^2 + 5x - 3) = 5x^2 + 10x - 4

Therefore, the sum is 5x^2 + 10x - 4.

Difference

The difference of the expression 2x^2 + 5x - 1 + 3x^2 + 5x - 3 is the result when the second expression is subtracted from the first expression. In this case, the difference is:

(2x^2 + 5x - 1) - (3x^2 + 5x - 3) = -x^2 + 2

Therefore, the difference is -x^2 + 2.

Product

The product of the expression 2x^2 + 5x - 1 + 3x^2 + 5x - 3 is the result when all the terms are multiplied together. In this case, the product is:

(2x^2 + 5x - 1) * (3x^2 + 5x - 3) = 6x^4 + 25x^3 - 11x^2 - 25x + 3

Therefore, the product is 6x^4 + 25x^3 - 11x^2 - 25x + 3.
