solution:
c²-121
c²-11²
(c+11)(c-11)
2. (x+5)(x-5)
x²-25
x²-5²
(x+5)(x-5)
3. 4(x+4)(x-4)
4x²-64
4(x²-16)
4(x+4)(x-4)
4. (x+3)²
x²+6x+9
x²+2x × 3+3²
(x+3)²
5. (y-5)²
y²-10y+25
y²-2y×5+5²
(y-5)²
6. (x-9)(x-3)
x²-12x+27
x²-9x-3x+27
(x²-9x)+(-3x+27)
x(x-9)-3(x-9)
(x-9)(x-3)
7. (x-9)(x+4)
x²-5x-36
x²-9x + 4x -36
(x²-9x)+(4x-36)
x(x-9)+4(x-9)
(x-9)(x+4)
8. (2x+1)(x+4)
2x²+9x+4
2x²+x+8x+4
(2x²+x)+(8x+4)
x(2x+1) + 4(2x+1)
(2x+1)(x+4
