Answer:

1.) (2x+3)²

= (2x+3)(2x+3)

= 4x²+6x+6x+9

= 4x²+12x+9

2.) (x-5)²

= (x-5)(x-5)

= x²-5x-5x+25

= x²-10x+25

3.) (a+3b-2c)²

= (a+3b-2c)(a+3b-2c)

= a²+3ab-2ac+3ab+9b²-6bc-2ac-6bc+4c²

= a²+3ab+3ab-2ac-2ac+9b²-6bc-6bc+4c²

= a²+6ab-4ac+9b²-12bc+4c²

4.) (3x-1)(3x+1)

= 9x²+3x-3x-1

= 9x²-1

5.) (x+5)³

= (x+5)(x+5)(x+5)

= (x²+5x+5x+25)(x+5)

= (x²+10x+25)(x+5)

= x³+10x²+25x+5x²+50x+125

= x³+10x²+5x²+25x+50x+125

= x³+15x²+75x+125

6.) (x-7)³

= (x-7)(x-7)(x-7)

= (x²-7x-7x+49)(x-7)

= (x²-14x+49)(x-7)

= x³-14x²+49x-7x²+98x-343

= x³-14x²-7x²+49x+98x-343

= x³-21x²+147x-343
