Ayuda! M + M = A + 2a + 9a = 6x2y2 - 12y2x2 + x2y2 = (3x3 - 5x2 + 3x + 2) + (2x3 + 4x2 - 5x - 1) = 3x2 * 4x5 = - 3x * 7x2 = ( - 5x2y3) : ( - 7xy2) = (2y - 3y)(2x + 6y2 - 4xy) = ( - 8x3 - 6x2 + 2x - 3)(2x6 - 5x5 + 7) =.

En resumen

M + M = 2MA + 2a + 2a = A + 13a6x2y2 - 12y2x2 + x2y2 = 24xy - 48xy + 4xy = - 20xy(3x3 - 5x2 + 3x + 2) + (2x3 + 4x2 - 5x - 1) = (9x - 10x + 3x + 2) + (6x + 8x - 5x - 1) = 11x + 13x2 * 4x5 = 6x * 20x = 120<img src="https://tex.z-dn.net/?
