  y = 5x² -30x +39

Step-by-step explanation:

Multiply it out and collect terms.

  y = 5(x -3)² -6

  y = 5(x² -6x +9) -6 . . . . . expand the square

  y = 5x² -30x +45 -6 . . . . use the distributive property

  y = 5x² -30x +39 . . . . . . collect terms

The expansion of a binomial square is ...

  (a +b)² = a² + 2ab + b²

In this problem, we have a=x, b=-3.
