Answer:
1) (x+y)² = x² + 2xy +y²
2 (p+6)² = p²+ 12p + 36
3) (2a - b)² = 4a² - 4ab + b²
4) ( 5l - 2m)² = 25l² - 20lm + 4m²
5) 9r² - 4s² = (9r-4s) (9r+4s)
6) (3s + 5t)² = 9s² + 30st + 25t²
7) (x-6y)² = x² - 12xy + 36y²
8) 9m - 16n = (3m-4n)² = 9m²- 24mn + 16n²
9) (5a + 7b)² = 25a² + 70ab + 49b²
10) (4x-6y)² = 16x² - 48xy + 36y²
Step-by-step explanation:
1) (x+y)² = x² + 2xy +y²
2 (p+6)² = p²+ 12p + 36
3) (2a - b)² = 4a² - 4ab + b²
4) ( 5l - 2m)² = 25l² - 20lm + 4m²
5) 9r² - 4s² = (9r-4s) (9r+4s)
6) (3s + 5t)² = 9s² + 30st + 25t²
7) (x-6y)² = x² - 12xy + 36y²
8) 9m - 16n = (3m-4n)² = 9m²- 24mn + 16n²
9) (5a + 7b)² = 25a² + 70ab + 49b²
10) (4x-6y)² = 16x² - 48xy + 36y²
