This tutorial, like our tutorial for the TI Plus and TI Plusprovides an introduction on how to create a simple program to solve the quadratic formula, which finds the zeros of a quadratic equation. On older calculators, this will be a drop-down menu reached by pressing the APPS button. You will be prompted to name your new program. If you choose the name of an existing program, your calculator will give you an error, so choose a unique name.
To be successful with these problems, most students will need some fairly strong guidance in the form of timely hints or questions to point their thinking in the right direction.
Problem 3 asks students to carefully examine the structure of a factored quadratic and recognize that once the roots of any quadratic are known - complex or real - that quadratic can be written in a factored form.
They should see the factored form as x - root x - root. Making use of structure MP7 like this is a powerful habit of thought! Problem 4 asks students to apply this new notion of factoring to the problem of the sum of two squares MP8.
They should recall from previous courses that the difference of two squares is always factorable into the sum and difference of the roots. Analogies like these can make mathematic come alive with beauty for many students! To factor a sum of two squares, they might set the sum of two squares equal to zero, find the solutions, and then write the factored form.
Homework 3 minutes Regardless of whether or not everyone has completed problems 3 and 4, I call a halt to all work a couple of minutes before the period ends. After what the students have done today, this should be fairly straightforward practice. They should make sure they see me in study hall for extra help if they need it!
Quads with Complex Solns.A much simpler function that uses a single input line without prompts and returns the answer to the home screen instead of program/io. How to use: type “qa(a,b,c)” into the home screen command line where a b and c are the respective coefficients after you have created the function below.
Solve these quadratic equation worksheets using zero product property, factorization, completing the square and quadratic formula. the roots are real or imaginary. In the difficult level, you should apply necessary substitution to write the quadratic equation in standard form and then solve by factorization method.
