36(x+2y)²-25(x-2y)²
=[6(x+2y]²-[5(x-2y)]²
=[6(x+2y)+5(x-2y)][6(x+2y)-5(x-2y)]
=(6x+12y+5x-10y)(6x+12y-5x+10y)
=(11x+2y)(x+22y)
=[6(x+2y]²-[5(x-2y)]²
=[6(x+2y)+5(x-2y)][6(x+2y)-5(x-2y)]
=(6x+12y+5x-10y)(6x+12y-5x+10y)
=(11x+2y)(x+22y)

解:原式=(6(X+2Y)+5(X-2Y))(6(X+2Y)-5(X-2Y))
=(6X+12Y+5X-10Y)(6X+12Y-5X+10Y)
=(11X+2Y)(X+22Y)
=(6X+12Y+5X-10Y)(6X+12Y-5X+10Y)
=(11X+2Y)(X+22Y)
