Ineed these math questions answered as soon as possible. i have no idea how to solve these last two questions on my test. in ! indentify the real roots and state their multiplicity. x^4 + 2x^3 - 23x^2 - 24x +1 44 = 0 a. root –4, multiplicity 2; root 3, multiplicity 2 b. root –4, multiplicity 1; root 3, multiplicity 2 c. root –4, multiplicity 2; root 3, multiplicity 1 d. root –4, multiplicity 1; root 3, multiplicity 1 find all possible rational roots of the following polynomial equation. 2x^3 + 3x^2 - 4x + 3 = 0
