Brackets :: Level 6

Expand algebraic expressions containing brackets and simplify the resulting expression in this self marking exercise.

Level 1 Level 2 Level 3 Level 4 Level 5 Level 6 Level 7 Level 8 Level 9 Level 10 Info Help

This is level 6: expanding products of two simple binomials. You can earn a trophy if you get at least 9 correct and you do this activity online.

Simplify the following expressions by removing the brackets. Order the terms in your answers so that variable terms come before the constants and the variables are in decreasing power order. Use the [²] button to insert a power of 2 into your answer .

\((a + 3)(a + 1)\)

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

"We all love your starters. It is so good to have such a collection. We use them for all age groups and abilities. Have particularly enjoyed KIM's game, as we have not used that for Mathematics before. Keep up the good work and thank you very much
Best wishes from Inger Kisby"

Comment recorded on the 3 October 'Starter of the Day' page by Fiona Bray, Cams Hill School:

"This is an excellent website. We all often use the starters as the pupils come in the door and get settled as we take the register."

Teacher! Are you delivering Maths lessons online?

Tutors! Are your tutorials now taking place via a video link?

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

This program checks your answers by matching the text you have typed in with the text it has as the correct answer. For that reason it does not recognise equivalent correct answers. For example the expansion of 3(2a+7) can be written as 6a+21 or 21+6a but the program only recognises the first option as the correct answer. Please type in your answers so that the terms are in order of decreasing powers of the variable.

Level 1 example: 5d - (2d + 2)

Remove the brackets to give 5d - 2d - 2
[note that everything inside the bracket is subtracted from 5d]
Collect like terms to give 3d - 2

Level 2 example: (9d - 7) - (5d - 2)

Remove the brackets to give 9d - 7 - 5d + 2
[note that negative 2 becomes positive due to the negative sign in front of the second bracket]
Collect like terms to give 4d - 5

Level 3 example: 4(2d + 4)

Multiply each term inside the bracket by 4 to give 8d + 16

Level 4 example: -5(5d + 4)

Multiply each term inside the bracket by negative 5 to give -25d - 20

Level 5 example: 4d(5d - 5)

Multiply each term inside the bracket by 4d to give 20d² - 20d

Level 6 example: (d + 7)(d - 2)

Multiply each term of the first bracket by each term of the second bracket to give d² + 7d - 2d - 14
Collect like terms to give d² + 5d - 14

F.O.I.L. First Outer Inner Last

Level 7 example: (4d + 7)(3d + 2)

Multiply each term of the first bracket by each term of the second bracket to give 12d² + 8d + 21d + 14
Collect like terms to give 12d² + 29d + 14

Level 8 example: (3d + 2)²

Write as (3d + 2)(3d + 2) then expand as in the previous example to give 9d² + 12d + 4

Level 9 example: 5(3d+1)-2(1-2d)

Multiply out the brackets to give 15d + 5 - 2 + 4d
Collect like terms to give 19d + 3

Level 10 example: (x+1)(2x-4)(x+2)

Multiply out the first pair of brackets to give (2x²+2x-4)(x+2)
Multiply each term in the first set of brackets by each of the terms in the second set of brackets then collect like terms to give 2x3 + 6x² - 8
