Beginning Factoring

First take the GCF, then apply the difference of squares:
2x² - 50

• (x-5)(x+5)

• (2x-10)(x+5)

• 2(x-5)(x+5)

• 2(x-25)(x+25)

Apply the difference of squares:
36x² - 49

• (7x-6)(7x+6)

• (6x+7)(6x+7)

• (6x+7)(6x-7)

• (6x-7)(6x-7)

Factor completely: 3x² - 7x + 2

• (x - 1) (3x + 2)

• (x - 2) (3x -1)

• (x - 1) (3x - 2)

• (x + 2) (3x + 1)

Multiply

(x - 7)(x + 7)

• x^2 + 7x - 49

• x^2 - 7x + 49

• x^2 - 49

• x^2 + 49

factor 10x²y – 30xy²

• xy(10 - 30)

• 10xy(x - 3y)

• 10x²y(3y)

• 10xy²(x)

Factor d² - 10d + 25

• (d + 5) (d - 5)

• (d - 15) (d + 10)

• (d + 5) (d - 20)

• (d - 5) (d - 5)
