x+ 1/x-2 = 2+ 1/x-1

2. The total area enclosed by lines y=|x| , |x|=1 and y=0 is

3. The minimum value of 3tan^2θ + 12cot^2θ is

4. If midpoint of join (x,y+1) and (x+1,y+2) is {3/2,5/2} then the midpoint of join of

(x-1,y+1) and (x+1, y-1) is

5. If pand q are roots of equation x^2+px+q=0, then

two values for p are

6.if the roots of x^2-ax+b=0 differ by unity then:

a. B^2=1+4a b. a^2 =1+4b c. if x belongs to real no.s, a^2>4b d. a^2 +4b =1

7. Total no. of solutions of

2^x+3^x+4^x-5^x=0 is

If a,b, c are three positive real numbers, then mnimum value of expression

b+c/a + a+c/b + a+b/c is
