If x' & x" are the roots (or x intercepts) of a quadratic equation, then it could be written:
y= (x-x')(x-x")
Since -6 & +6 are the roots of the quadratic function, then it could be written
as follows y= (x+6)(x+6) ===> y= x²-36. So the answer is B
No, she will still owe $9.30. $25.63 - $16.33= $9.30
