Simplifying products and quotients
Multiplying out brackets
Factorising
Completing the square
Algebraic fractions
Initial learning for this qualification will enable learners to:
Understand and use the concepts and vocabulary of expressions, equations, formulae, inequalities, terms and factors.
Simplify algebraic expressions by collecting like terms.
e.g. 2a + 3a = 5a
Simplify algebraic products and quotients.
e.g. a x a x a = a³
2a x 3b = 6ab
a² x a³ = a5
3a³ ÷ a = 3a²
Simplify algebraic expressions by multiplying a single term over a bracket.
e.g. 2 (a+3b) = 2a + 6b
2(a+3b) + 3(a – 2b) = 5a
Take out common factors.
3a – 9b = 3(a-3b)
2x + 3x² = x(2 + 3x)
Foundation tier learners should also be able to:
Expand products of two binomials.
(x-1)(x-2) = x² – 3x + 2
(a+2b) (a-b) = a² + ab – 2b²
Factorise quadratic expressions of the form
e.g. x² -x -6 = (x-3) (x+2)
x² – 16 = (x-4) (x+4)
x² – 3 = (x – √3)(x +√3)
Higher tier learners should additionally be able to:
Simplify algebraic products and quotients using the laws of indices.
e.g. a½ x 2a¯³ = 2a-5/2
2a² b³ ÷ 4a¯³ b = 1/2 a5 b²
Expand products of more than two binomials.
e.g. (x+1)(x-1)(2x+1) = 2x³ + x² – 2x -1
Factorise quadratic expressions of the form ax² + bx + c (where a ≠ 0 or 1)
e.g.
2x² + 3x -2 = (2x -1 ) (x+2)
Complete the square on a
quadratic expression.
x² + 4x – 6 = (x+2)² – 10
2x² +5x+1 = 2 (x + 5/2)² – 17/8
Simplify and manipulate algebraic fractions.
e.g. Write (1/n-1 ) + (n/n+1) as a single fraction.
Simplify (n² + 2n) / (n² + n -2)
