Question

9x² + 6xy + y² ? solve using identities!​

Answer 1

Step-by-step explanation:

9x² + 6xy + y² => (3x)² + 2 (3x)(y) + (y)² => (3x+y)² => (3x+y) (3x+y)

4y² - 4y + 1. => (2y)² - 2 (2y)(1) + (1)² => (2y - 1)² => (2y-1) (2y-1)

x² - y² / 100.

Answer 2

Answer:

$9 {x}^{2} + 3xy + 3xy + {y}^{2} \\ (9 {x }^{2} + 3xy) + (3xy + {y}^{2} ) \\ 3x(3x + y) \: y (3x + y) \\ (3x + y) \: (3x + y)or \ \: {(3x + y)}^{2}$
