2C Expanding algebraic expressions
LEARNING INTENTIONS:
To understand how the distributive law is used to expand brackets
To be able to expand brackets by multiplying through by the term outside the bracket
To know to expand brackets first before collecting like terms when simplifying algebraic expressions
SUCCESS CRITERIA:
I can expand brackets and simplify.
e.g. Expand 4𝑥(3𝑥−5)4x(3x−5).
I can simplify by removing brackets.
e.g. Expand and simplify 7−3(3𝑥−2)7−3(3x−2).
