Answer:

  • x² + 22x
  • Quadratic Binomial

Explanation:

[tex]\rightarrow 3x(2x +4) -5(x^2 - 2x)[/tex]

[tex]\rightarrow 6x^2 +12x -5x^2 + 10x[/tex]

[tex]\rightarrow 6x^2 -5x^2+12x + 10x[/tex]

[tex]\rightarrow x^2 +22x[/tex]

As the above polynomial has two terms and highest power of 2, the polynomial is a Quadratic Binomial

The answerrrrrrrrdrrrrrrrrrrrrrrr
