-4x + 6x^2 + 5x Please help me

my choices are

A) 7x^3

B) 6x^2 - 9x

C) 6x^2 - 9x

D) 6x^2 + x

well, 5x-4x = x, so what do you think?

So D?

looks good to me

Okay! Thank you!

Of course! To simplify the expression -4x + 6x^2 + 5x, you need to combine like terms.

First, let's identify the like terms. Like terms have the same variable raised to the same power.

In this expression, we have three terms: -4x, 6x^2, and 5x.

Since -4x and 5x have the same variable (x) raised to the first power, they can be combined.

-4x + 5x = (6 -4 + 5)x = 7x.

Now we have 7x + 6x^2. Since these terms have different variables or different powers of the same variable, they cannot be combined any further.

Hence, the simplified form of the expression -4x + 6x^2 + 5x is 6x^2 + 7x.
