Question

(5x²+6x-3)-(2x²-3x-4)=?

Answer 1

Решение данного примера:
(5x^2+6x-3)-(2x^2-3x-4)=5x^2+6x-3-2x^2+3x+4=3x^2+9x+1

Answer 2

To solve the expression, you can begin by distributing the negative sign to the terms inside the parentheses and then combine like terms:

(5x² + 6x - 3) - (2x² - 3x - 4)

First, distribute the negative sign:

5x² + 6x - 3 - 2x² + 3x + 4

Next, combine like terms. Start with the terms involving x²:

(5x² - 2x²) + 6x + 3x - 3 + 4

Simplifying further:

3x² + 9x + 1

So, (5x² + 6x - 3) - (2x² - 3x - 4) simplifies to 3x² + 9x + 1.
