Question

Explain whether the polynomials below are written in standard form. If not, use complete sentences to explain how to write the polynomial in standard form. 
3a3b – 4ab2 + a2
–8x2y2 + 10xy4 – 6x2y

phi · Answer

they would (and so should you) want the variables in alphabetical order, highest order (that is the exponent) to lowest exponent.
Sort by a to the highest power to the lowest power
$$ 3a^3b^1 - 4a^1b^2 +a^2 $$

cna you help me please cause i dont get it

phi · Answer

$$ 3a^3b^1 - 4a^1b^2 +a^2b^0 $$
Find the term with a (because a comes before b) to the highest power. That is the first term.
Now find a to the next highest power. that is the 2nd term.
