If the question is about

the remainder for 2x4 + 5x3 - 17x2 - 5 divided by x + 3

by the remainder theorem, to get the answer you first find the value of x tha t makes x + 3 = 0. That is x = -3.

You then substitute this value in the "numerator" expression:

Thus remainder = 2*(-3)4 + 5*(-3)3 - 17*(-3)2 - 5

= 2*81 - 5*27 - 17*9 - 5 = -131

How do you simplify simplify 6x7y4(2x4-5xy) How do you simplify 25x9 -10x35x3 how to simpllify x2-12x plus 3549-x2 and simplify x-7x2-4x-21?

In the future, ask four questions as four separate questions to limit confusion. 6x7y4(2x4 - 5xy) could be written as 6x8y4(2x3 - 5y) Either way, once you carry out the multiplication, it becomes 12x11y4 - 30x8y5 I'm guessing the second problem is 25x9 - 10x3 + 5x3 since this website can't reproduce plus signs. That becomes 25x9 - 5x3 which factors to 5x3(5x6 - 1) x^2 and -x^2 cancel each other out, leaving 3549 - 12x which factors to 3(1183 - 4x) -7x^2 - 3x - 21 can be written as -(7x^2 + 3x + 21) but the solution isn't rational.
