Question

Which polynomial is in standard form?

2x-3x+ 10x
-16x2-9x+12
15x-6x2+3
-7x?+ 9x9 - 11x

Answer 1

`-16x^2-9x+12`

Explanation:

`2x-3x+ 10x`

`-16x^2-9x+12`

`15x-6x^2+3`

`-7x+ 9x^9 - 11x`

Standard form is when the polynomial's terms's degrees go down so the highest power is the first and the lowest is the last.

We see that the first expression can be more simplified so that isn't right.

We see that the second expression is in standard form so that might be right.

We see that the third expression has the highest power as the second term so that is wrong

We see that last expression is the same as the third one so that is also wrong.

We can conclude that
`-16x^2-9x+12` is the correct one or in standard form.
