Question

Помогите решить пример по алгебре! Срочно нужно!!!! Нужно преобразовать выражения в многочлен (7х во второй степени-4х+8)-(4х во второй степени+х-5)=?

Answer 1

$(7x^2-4x+8)-(4x^2+x-5)=\\\\=7x^2-4x+8-4x^2-x+5=3x^2-5x+13$

Answer 2

Algebraic Expression Transformation

To transform the given expressions into a polynomial, we start by simplifying the expressions and then combining like terms.

The given expressions are: 1. \(7x^2 - 4x + 8\) 2. \(-(4x^2 + x - 5)\)

Simplifying the Expressions

Let's simplify the second expression by distributing the negative sign: \(-(4x^2 + x - 5) = -4x^2 - x + 5\)

Now, we can combine the two expressions: \(7x^2 - 4x + 8 - 4x^2 - x + 5\)

Combining Like Terms

Combining like terms, we get: \(7x^2 - 4x^2 - 4x - x + 8 + 5\) \(3x^2 - 5x + 13\)

So, the given expressions transformed into a polynomial is \(3x^2 - 5x + 13\).
