Answer:
(a) (3x + 5y)² = [(3x)² + (2) (3x) (5y) + (5y)²]
= 9x² + 25y² + 30xy
(b) (17a - 4)² = [(17a)² - (2) (17a) (4) + (-4)²]
= 289a² - 136a + 16
(c) (2p/3 - 12)² = [(2p/3)² - (2) (2p/3) (12) + (-12)²]
= 4p²/9 - 16p + 144
(d) (11 + 8p)² = [(11)² + (2) (11) (8p) + (8p)²]
= 64p² + 176p + 121
(e) (p + q/3) (p - q/3) = [p² - (q/3)²]
= p² - q²/9
(f) (2a - 7a)² = [(2a)² - (2) (2a) (7a) + (7a)²]
= 4a² - 28a² + 49a²
= 25a²
(g) (7b - 2a)² = [(7b)² - (2) (7b) (2a) + (-2a)²]
= 4a² + 49b² - 28ab
(h) (x + 17) (x - 17) = [(x)² - (17)²]
= x² - 289
(i) (2x² + 1)² = [(2x²)² + (2) (2x²) (1) + (1)]
= 4x⁴ + 4x² + 1
