Basic Algebra

Simplify these algebraic expressions containing powers.

Multiply out the brackets and simplify your answers where possible:
Use the Maths Symbols Pad for squared terms and square roots, etc.,

² ³ % x y z ( ) { } + - * / = ÷

This Maths pad will append characters to the active input. That is the question you are currently answering.

1 - Multiply out the brackets.

  1. (2 + 3x)(3x – 1 )
    No such question type as Set qData['type'] to valid type. Eg "input" , "select" or "textarea" ... X
  2. (3x + 2)(2x – 4)
    No such question type as Set qData['type'] to valid type. Eg "input" , "select" or "textarea" ... X
  3. (x – 3 ) (4x + 1 )
    No such question type as Set qData['type'] to valid type. Eg "input" , "select" or "textarea" ... X
  4. 4(x + 2y)(3x – 2y)
    No such question type as Set qData['type'] to valid type. Eg "input" , "select" or "textarea" ... X
