I assume u^2x means u^2 * x. Factoring the individual terms of the expression, we have 5^1 * x^3 - 5^3 * u^2 * x^1. Obviously, they have a factor 5^1 * x^1 in common, which we can pull out, giving us 5 * x * (x^2 - 5^2 * u^2). The last factor is the difference of two squares, which can be rewritten a well-known product, and we find the factoring
All you're able to be able to desire to do is multiply out each and all of the brackets and evaluate the result with the question. a) 5x2(x - a million) - a million(x - a million) = 5x^3 - 5x^2 - x + a million it relatively is real b) the two on the lower back will multiply the 5x^2 on the front to furnish a term in 10x^3 it relatively is obviously incorrect. c)(x - a million)(5x2- a million) = 5x^3 - x - 5x^2 + a million it relatively is likewise maximum suitable suited. yet, the format used right here is the extra time-honored thank you to write down the standards. So i could decide for this answer. d) This answer is incomprehensible.

5 * x * (x - 5*u) * (x + 5*u).
