(3x + 4)^2 = (3x)^2 + 2 * 4 * 3x + (4)^2
(3x + 4)^2 = 9x^2 + 24x + 16
(2x - 8)^2 = (2x)^2 + 2 * (-8) * 2x + (-8)^2
(2x - 8)^2 = 4x^2 - 32x + 64
(5x - 2)(5x + 2) = (5x)^2 - (2)^2
(5x - 2)(5x + 2) = 25x^2 - 4
(-2x - 4)^2 = (-2x)^2 + 2 * (-4) * (-2x) + (-4)^2
(-2x - 4)^2 = 4x^2 + 16x + 16

(3x + 4)² = 3x * 3x + 3x * 2 * 4 + 4² = 9x² + 24x + 16
(2x - 8)² = 2x * 2x + 2x * - 8 * 2 + (-8)² = 4x² - 32x + 64
(5x - 2)(5x + 2) = 5x² - 2² = 25x² - 4
(-2x - 4)² = (-2x)² + -2x * -4 * 2 + (-4)² = 4x² + 16x + 16

(3x + 4)² = 3x * 3x + 3x * 2 * 4 + 4² = 9x² + 24x + 16(2x - 8)² = 2x * 2x + 2x * - 8 * 2 + (-8)² = 4x² - 32x + 64
