Question: Form a polynomial f(x) with real coefficients having the given degree and zeros. Degree: 4; Zeros: -4+2i; -3 multiplicity 2. It asks me to enter the polynomial. I got this...f(x) = a(x^4-2x^3-19x^2+48x+180 Which is wrong.. I HAVE NO CLUE WHAT I AM DOING WRONG OR WHAT THE RIGHT ANSWER IS!?!?! RAGE!!!! Please help ;)

-4+2i is a root, so is -4-2i x= -4+/-2i x+4 = +/-2i ==> (x+4)^2 = -4 ==> x^2+8x+20 = 0 so x^2+8x+20 is a factor. -3 is a root with multiplicity 2. So (x+3)^2 is another factor. f(x) = a[(x+3)^2][x^2+8x+20]

1. 25k = -25 k= -1 2. 24 + h =4 * 10 h = 40 -24 h = 16 3. -9 * 3 = 15 + v -27 - 25 = v v = -52 4. -17 + q = 8 * 13 q = 104 + 17 q = 121 5. 8m = -7 + 14 8m = 7 m = 7/8

25k + 12 = 13 1. subtract 12 from bothe sides 25k = -25 2. divide both sides by 25 k = -1 24 + h/4 = 10 1. subtract 24 from both sides h/4 = -14 2. multiply both sides by 4 h = -56 Basically just do reverse operations! comment if you need help on the rest
