Aquadratic function has a line of symmetry at x = –3 and a zero at 4. what is the distance from the given zero to the line of symmetry? what is the other zero of the quadratic function?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
