a. (x + 5)² = (x + 5)(x + 5)
= x² + 5x + 5x + 25
= x² + 10x + 25
b. (x - 3)² = (x - 3)(x - 3)
= x² - 3x - 3x + 9
= x² - 6x + 9
c. (3a²)³ = 3³a⁶
= 27a⁶
d. (6 + p)² = (6 + p)(6 + p)
= 36 + 6p + 6p + p²
= 36 + 12p + p²
I hope this hepls:)
(a + b)² = a² - 2ab + b²
(a - b)² = a² - 2ab + b²
a. (x + 5)
(a + b)² = a² + 2ab + b²
(x + 5) = x² + 2 · 5x + 5²
(x + 5) = x² + 10x + 25
b. (x - 3)²
(a - b)² = a² - 2ab + b²
(x - 3)² = x² - 2 · 3x + 3²
(x - 3)² = x² - 6x + 9
c. (3a²)³
d. (6 + p)²
(a + b)² = a² + 2ab + b²
(6 + p)² = 6² + 2 · 6p + p²
(6 + p)² = 36 + 12p + p²
