1. x³ + 5x² + 4x
= x(x² + 5x + 4)
= x(x + 4)(x + 1)
2. 30x²+25x
= 5x(6x + 5)
3. 9x - x³ - 3x²
= -x(x² + 3x - 9)
4. 4x+8x²
= 4x(2x +1)
5. x² - 25
= (x + 5)(x - 5)

X^3 + 5X^2 + 4X = X(X^2 + 5X + 4) = X(X + 4)(X + 1)
30X^2 + 25X = 5X(6X + 25)
9X - X^3 - 3X^2 = -X(X^2 + 3X - 9)
4X + 8X^2 = 4X(2X + 1)
X^2 - 25 = (X + 5)(X - 5)
