Equations, Formulae and Identities - objectives
Step 6
Construct and solve linear
equations with integer coefficients (unknown on either or both sides, without and with brackets) using
appropriate methods (e.g. inverse operations, transforming both sides in same way). View step.
Simplify or transform linear expressions by collecting like terms; multiply a single term over a bracket. View step.
Substitute integers into simple formulae. View step.
Step 7
Construct and solve linear equations
with integer coefficients (with and without brackets, with
negative signs anywhere in the equation, and with a positive or negative
solution) using an appropriate method. View
step.
Step 8
Use systematic trial and improvement
methods and ICT tools to find approximate solutions to equations such
as x³ + x = 20. View
step.
Transform algebraic expressions by factorising to produce a single term multiplied by terms in a bracket. View step.
Step 9
Square a linear expression, expand the product of two linear expressions of the form x ± n and simplify the corresponding quadratic expression. View step.
Step 10
Solve a pair of simultaneous linear equations by eliminating one variable; link a graphical representation of an equation or pair of equations to the algebraic solution. View step.
