C1 - Algebra
And Functions
- Simplifying expressions by
collecting like terms
- When simplifying expressions
remember to look out for like terms
that you can either subtract or add to
simplify the expression.
- 4x - 5y + 3x + 6y
= 7x + y
- When simplifying expressions
remember to look out for like terms
that you can either subtract or add to
simplify the expression.
- The Rules Of Indices
- When you are X two values
together you are adding the
powers and multiplying the numbers
- When you are / two values
together you are taking away the
powers and dividing the numbers
- When you are X two values
together you are adding the
powers and multiplying the numbers
- Expanding An Expression
- The sign outside of the bracket
changes the sign of every term
inside the brackets
- 5(2x + 3) = 10x + 15
- The sign outside of the bracket
changes the sign of every term
inside the brackets
- Factorising Expressions
- When you factorise an expression the
terms inside should now not have a
common factor
- 3x + 9 = 3(x + 3)
- When you factorise an expression the
terms inside should now not have a
common factor
- Factorising quadratic
expressions
- quadratic expression is
written as ax*2 + bx + c
where a, b, c are constants
- 6x*2 + 9x = 3x(2x + 3)
- quadratic expression is
written as ax*2 + bx + c
where a, b, c are constants
- The rules of indices for all
rational exponents
- They can be written as a/b
where a and b are both
integers
- x*-4 / x*-3
= x*7
- They can be written as a/b
where a and b are both
integers
- The use and manipulation of surds
- The square root
of a number is a
surd
- The square root
of a number is a
surd
- Rationalising the denominator of
a fraction when it is a surd
