2. Multiplication of Algebraic Expressions
When we multiply algebraic expressions, we need to remember the Index Laws from the Numbers chapter.
Let's see how algebra multiplication works with a series of examples.
Multiply x3(x4 + 5a)
Multiply (x + 5)(a − 6)
Multiply (2x + 3)(x2 − x − 5)
Multiply `(x − 3)^2`
`(x − 3)^2`
is NOT equal to
Please take note of this! Many students confuse this idea. (See also Towards more meaningful math notation for a discussion on this issue.)
Simplify 5x[−4 + 10(x − y)] + 7x
