# Algebra | Expressions, Factorising and Replacing Letters With Numbers

I am a two weeks late in uploading this worksheet, but I was catching up with homework.

This worksheet covers whats listed in the title itself, and I have included an example for each topic.

You may print and download and share it to students and even adults to improve their knowledge.

This worksheet will go into my maths exam booklet when it comes to the exam prep.

Algebra:

Expanding single brackets:

E.g. 5(a-4)= 5 x a= 5a, 5 x 4= 20 = 5a-20

1) 6(n+2)=

2) y(2y-2)=

3) 3(7-4w)=

4) 5p(2p+3)=

5) 3(2a-5)=

6) 4(2x-1) =3(4x+7)=

7) 5(6y+2x) -4(3x+2y)=

8) Y(2y+3) -2(y-4)=

9) X(x+3) +5(x-2)=

10) 6(4-2x) -3(5+3x)=

Factorising expressions:

E.g. 2x +6= 2 x X= 2x, 2 x 3= 6 = 2(x+3)

1) 6y +2=

2) 12x +4y=

3) 3x² +4x=

4) 15b -5=

5) 7c -3c²=

6) 12a²b +18ab²=

7) 4x²y + 6xy² - 2xy=

8) 9c²d + 15cd²=

9) 4a²b + 8ab² +12ab=

10) 8a + 6a²=

Replacing letters with numbers:

To find the value of these expressions: a=2, b=5 and c=3.

1) 5c + 2a=

2) 4(5b-2a)=

3) 2a + 4b 8c=

4) 2(a + b + c)=

5) 3b + c=

To work out the value of these expressions: p=3, q=2, r=5 and s=0.

1) P +r=

2) 4(p+7)=

3) Pqr=
