Question

Is this right?

Yes, 3a^3b – 4ab^2 + a^2 is written in standard form. 3a^3b is the highest term because a has a power of 3. In -4ab^2, b only has a power of 2. Lastly, in a^2, a only has a power of 2 and no other variables so it is the lowest term and a polynomial written in standard form is written from highest to lowest.

No, -8x^2y^2 + 10xy^4 – 6x^2y is not written in standard form because 10xy^4 has a higher power than -8x^2y^2. To write the equation in standard form you have to make 10xy^4 the first term, then make -8x^2y^2 the second term and -6x^2y is where it should be.

Answer 1

both are correct
