About this worksheet

Expand and factor expressions. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can write 4(2x + 3) as 8x + 12 and -2(x + 3) as -2x − 6, multiplying every term inside the parentheses.
  • I can expand and join like terms, like 3(x + 2) + 4x = 7x + 6, and subtract parentheses, like 8x − 3(2x − 5) = 2x + 15.
  • I can pull a common factor out of 8x + 20 to get 4(2x + 5), and take out the greatest one.

Standard: 7.EE.A.1

Words to know

expand: Write an expression in parentheses without the parentheses, like 3(x + 2) = 3x + 6.

factor (verb): Pull a common number out and put the rest in parentheses, like 3x + 6 = 3(x + 2).

factor (noun): A number that divides each term evenly. 3 is a factor of 3x and 6.

greatest common factor: The biggest number that divides every term evenly.

distribute: Multiply the number outside the parentheses by every term inside.

coefficient: The number multiplying the letter. In 3x + 4 it is 3.

Common mistakes

Your child multiplied only the first term inside the parentheses, so the second term stayed as it was.

Your child multiplied both terms but lost the minus sign on the second one. Try circling the minus sign before multiplying, and keep it with its number.

Your child multiplied both terms but the minus sign in front only reached the first one.

What to say
