Answer 2

1. ( x - 25 )² = (x-25)(x-25) = x.x-x.25-25.x+25.25 = x²-50x+625
2. ( 3x - 4 )² = (3x-4)(3x-4) = 3x.3x-3x.4-4.3x+4.4 = 9x²-24x+16
3. ( x + 3 )² = (x+3)(x+3) = x.x+x.3+3.x+3.3 = x²+6x+9
4. ( 5x + 6 )² = (5x+6)(5x+6) = 5x.5x+5x.6+6.5x+6.6 = 25x²+60x+36
5. ( x - 2y )² = (x-2y)(x-2y) = x.x-x.2y-2y.x+2y.2y = x²-4xy+4y²
