Algebraic Manipulation
- Expanding Brackets
- To expand or multiply out this
expression we multiply every term
inside the bracket by the them
outside the bracket
- 3y(4-2y)= 12y-6y^2
- when there is a negative term
outside the bracket , the signs of the
multiple terms change
- To expand or multiply out this
expression we multiply every term
inside the bracket by the them
outside the bracket
- Simplifying brackets
- sometimes you need to
expand the bracket and
the simplify the bracket
- 3x+2x(5-x)=3x+10x-2x^2=13x-2x^2
- 3x+2x(5-x)=3x+10x-2x^2=13x-2x^2
- sometimes you need to
expand the bracket and
the simplify the bracket
- Expanding Two Brackets
- to multiply two brackets we multiply every
term in the second bracket to every term in
the first bracket
- (x+y)(x+y) =
x^2+xy+y^2
- with practice you can expand
two brackets in a simpler form
- to multiply two brackets we multiply every
term in the second bracket to every term in
the first bracket
- Squaring Expressions
- (2-3a)^2=4-12a+9a^2
- the first term is squared
- the second one is the
product of the two
terms
- the third one is squared
- (2-3a)^2=4-12a+9a^2
- differences between two
squares
- when we simplify the
two the middle number
cancel out
- (a-b)(a+b)=A^2-b^2
- when we simplify the
two the middle number
cancel out
