range of √9+x^2
answer this soon​

Answer 1

Answer:

9 + 6x + x²

Step-by-step explanation:

√9 = 3

Therefore, 3+x^2 = (3+x)²

= (3)² + 2.3.x + (x)²

= 9 + 6x + x²

or, 9 + (3+3)x + x²

or, 9 + (3+3)x + x² = 9 + 3x + 3x + x²

or, 9 + (3+3)x + x² = 9 + 3x + 3x + x² = 3(3+x) + x(3+x)

or, 9 + (3+3)x + x² = 9 + 3x + 3x + x² = 3(3+x) + x(3+x) = (3+x)(3+x) [Answer Proved]
