Expand and combine like terms. (2x^4+3x^3)(2x^4-3x^3)

Step-by-step explanation:

Use the form (a + b)(a - b) = a^2 - b^2:

(2x^4 + 3x^3)(2x^4 - 3x^3) = 4x^8 - 9x^6.

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
