Question

What is the standard form of `y=(2x + 3)(3x-6)`?

Answer 1

`y=6x^2-3x-18`

Explanation:

Standard form = Exponents in descending order.

First, expand the brackets using FOIL. See: How do you FOIL `(7-a)^2`? for more info.

`y=(2x*3x)+(2x*-6)+(3*3x)+(3*-6)`
`y=6x^2-12x+9x-18`
`y=6x^2-3x-18`

That is already in standard form/descending order.
