Answer:
Step-by-step explanation:
We want to write the quadratic equation whose roots are 2 and -2, and whose leading coefficient is 4.
Since 2 and -2 are roots, are factors of this quadratic function.
The factored form is given as:
Since the leading coefficient is 4, a=4
Therefore the equation becomes:
Recognize and expand using difference two squares.
The required equation is:
