# How do you write #y= 3(x-3)^2-12# in standard form?

Each term in the second bracket is multiplied by each term in the first bracket. This can be achieved as follows.

distribute the brackets.

If you know the FOIL method then you can use it.

The function is now.

distributing by 3 gives.

To write the equation y = 3(x - 3)^2 - 12 in standard form, expand and simplify it:

y = 3(x^2 - 6x + 9) - 12 y = 3x^2 - 18x + 27 - 12 y = 3x^2 - 18x + 15

So, the standard form of the given equation is: y = 3x^2 - 18x + 15
