( d – 5)^6 =(d^410d+25d10d+100d250d+25d250d+625)(d10d+25)=(d^420d+150d500d+625)(d10d+25)=d^610d^5+25d^420d^5+200d^4500d+150d^41500d+3750d500d+5000d12500d+625d6250d+15625=d^630d^5+375d^42500d+9375d18750d+15625 21. Explain how to find the degree of a polynomial. To find the degree of a polynomial its the same number term of highest degree. for an example, if u have terms 5 10 15 20, 20 would be the degree.

Best ResponseYou've already chosen the best response.1\[27x^3 + 125 = 0\] factor the sum of two cubes as \[(3x+5)(3x^215x+25)\] first one gives you your answer, quadratic formula gives the answer for the two complex roots of \(3x^215x+25\)

Best ResponseYou've already chosen the best response.1For your first problem (# 23), you will have 2 solutions because of the absolute value expression. Case #1: For x > 9/8 9(8x  9) = 2x + 3 > x = 1.2 Case #2: For x <= 9/8 9(9  8x) = 2x + 3 > x = 39/37

Best ResponseYou've already chosen the best response.1thx, @satellite73 you saved me a bunch of typing. Great approach, explanation, and theory. Just a typo, as we all do that from timetotime.
