Multiple Choice Question

10 x 1 = 10

(a)
7

(a)
2b² = 9ac

(d)
x²+ 4x + 10 = 0

(b)
2

(a)
x ∈ (10, ∞)

\(\frac{1-2 x}{3+2 x-x^{2}}= \frac{\mathrm{A}}{3-x}+\frac{\mathrm{B}}{x+1} \)
\( 1-2 x=\mathrm{A}(x+1)+\mathrm{B}(3-x) \)
\( \text { Put } x=3,-5=\mathrm{A}(4) \Rightarrow \mathrm{A}=\frac{-5}{4} \)
\( \text { Put } x=-1,3=\mathrm{B}(4) \Rightarrow \mathrm{B}=\frac{3}{4} \)
\(\mathrm{~A}+\mathrm{B}= \frac{-5}{4}+\frac{3}{4}=\frac{-2}{4}=\frac{-1}{2} \)

\(x^{2}-\mathrm{k} x+\mathrm{c}=0\)
a and b are the roots
\(\therefore a+b=k, a b=c\)
To find
\(\sqrt{(a-b)^{2}+0^{2}}=a-b=\sqrt{(a+b)^{2}-4 a b}=\sqrt{k^{2}-4 c}\)
