• Write the answer

Factor
10x² + 15x-5

• 25(10x³+45x-15)

• 5(2x³ + 3x²-x)

• x(10x³+15x-5)

• 5(2x²+3x-1)

Factor Completely:  6x² + 5x - 6

• 6(x + 1)(x - 6)

• (6x + 6)(x - 1)

• (2x - 3)(3x + 2)

• (3x - 2)(2x + 3)

x² + 18x + 81

• (x + 9)(x – 9)

• (x + 18)(x + 18)

• (x + 9)(x + 9)

• (x + 6)(x + 6)
