Skills for this week’s quiz

November 26, 2012 Leave a comment Go to comments

Be sure you are comfortable with the following:

  • Expanding brackets, e.g. Write 2(x-3)(2x+5) in standard form
  •  Factoring quadratic expressions, e.g. Write 2x2+ 5x + 2 in factored form. This includes:
    •  Differences of squares, e.g. 9x2 – 36
    •  Perfect squares, e.g. 9x2 + 12x + 4
    •  Expressions that require the removal of a common factor, e.g. 2x2 + 6x – 8
    •  Expressions in which a > 0, e.g. 3x2 + x – 2
  • Sketching and labelling main features of a quadratic from its equation:
    • vertex
    • axis of symmetry
    • zeroes
    • shape
    • function
  • Finding the equation of a quadratic from its sketch
  • Finding the equation of a quadratic given its zeroes and its y-intercept only
  • Answering concept questions in the context of a real-world example
