Question

(7x^2-4x+8)-(4x^2+x-5)

Answer 1

Ответ:

3x²-5x+13

Объяснение:

$(7x^{2}-4x+8) -(4x^{2} +x-5)$

7x²-4x+8-4x²-x+5 = 3x²-5x+13

Answer 2

To simplify the expression $(7x^2 - 4x + 8) - (4x^2 + x - 5)$, you can perform the subtraction of each term separately. Here's the step-by-step process:

1. Distribute the negative sign through the parentheses:

   $7x^2 - 4x + 8 - 4x^2 - x + 5$

2. Combine like terms by grouping the terms with the same variable exponent:

   $(7x^2 - 4x^2) + (-4x - x) + (8 + 5)$

3. Simplify the terms within each group:

   $3x^2 - 5x + 13$

So, the simplified form of the expression $(7x^2 - 4x + 8) - (4x^2 + x - 5)$ is $3x^2 - 5x + 13$.
