Question

Which of the following represents the correct standard form of the sum of (x + 4) and (x² + 2x)?

पर्याय

• 3x + x² + 4

• x² + 3x + 4

• x³ + 6

• 2x² + 6

Answer 1

x² + 3x + 4

Explanation:

Standard form requires terms to be ordered by degree (highest power first).

Combining like terms gives x² + (1x + 2x) + 4, which is x² + 3x + 4.
