Question

What is the standard form of `y= (3x-5)(2x+12)-7x^2+15x`?

Answer 1

`y = -x^2+41x -60`

Explanation:

To get the standard form, multiply out to get rid of the brackets and then group the like items and order in descending order of powers.

`y=(6x^2 -10x+36x-60) - 7x^2 +15x`
`y = -x^2+41x -60`
