Formative 3

The process of expressing an algebraic expression in terms of its factors is called _____.

• equation

• rational numbers

• factorization

• sentence

Change of subject of a formula means______.

• Rearranging the formula so that a different letter or symbol become the subject

• replacing the letter of the subject

• Dividing both sides by a certain symbol

• None of the above

• Divide both sides by 10

• Add 7 to both sides

• Multiply both sides by 5

• Divide both sides by 5

Factor:

x² + 11x + 24

• (x + 6)(x + 4)

• (x + 12)(x + 2)

• (x - 8)(x - 3)

• (x + 8)(x + 3)

Factor:
18b²-9b³

• 9b²(18-9b)
• 9b²(2-b)
• 9b²(18-9b²)
• b²(2-b²)

Factor (hint...take out the greatest common factor first)
2c² + 2c - 84

• (c-6)(2c+14)
• (c+7)(2c-12)
• (c-4)(2c+21)
• 2(c+7)(c-6)
