What is the standard form of # y= (2x-7)^3-(2x-9)^2#?
Standard form just means that the highest degree term (the variable with the biggest exponent) is first, and they continue in descending order. So
That's the first part in standard form!
We've got both parts, so let's subtract:
Now just combine like terms, and don't forget to change the signs of the terms in the expression that is being subtracted:
Not so bad, right? Hope this helps!
