Explicación paso a paso:
Formula de binomio al cuadrado: (a ± b)² = a² ± 2ab + b²
(2x+1)² = 4x²+4x+1
(3x+2)² = 9x²+12x+4
(x+3)² = x²+6x+9
(2x+5)² = 4x²+20x+25
(5x+3y)² = 25x²+30xy+9y²
(3x-1)² = 9x²-6x+1
(2x-3)² = 4x²-12x+9
(x-2)² = x²-4x+4
(2x-5)² = 4x²-20x+25
(3x-2y)² = 9x²-12xy+4y²
Formula de binomios conjugados: (a + b)(a - b) = a² - b²
(x+1)(x-1) = x²-1
(3x+2)(3x-2) = 9x²-4
(2x+3)(2x-3) = 4x²-9
(5x-2y)(5x+2y) = 25x²-4y²
(2x+3y)(2x-3y) = 4x²-9y²
