Quadratic Equations
If 3x + 1/2x = 5, then the value of 8x3 1/27 x3 is

a) 118.5
b) 30.37037037
c) 0
d) 1



Answer
Solution
Correct Answer Is : 30.37037037
Solution Is :
If the average of x and 1/x (x Not Equal 0) is M, the the average of x2 and 1/x2 is

a) 1 - M2
b) 1 - 2M
c) 2M2 - 1
d) 2M2 + 1



Answer
Solution
Correct Answer Is : 2M2 - 1
Solution Is :
If a, b and c are real and a2 + b2 + c2 = 2(a - b - c) - 3 then the value of 2a - 3b + 4c is

a) -1
b) 0
c) 1
d) 2



Answer
Solution
Correct Answer Is : 1
Solution Is :
If x + y = z, then the expression x3 + y3 - y3 + 3xyz will be eqal to

a) 0
b) 3xyz
c) -3xyz
d) Y3



Answer
Solution
Correct Answer Is : 0
Solution Is :
If x + 1/x = 5 , then the value of 2x / ( 3x2 - 5x + 3 ) is

a) 2
b) 1 1/5
c) 1/5
d) 3/5



Answer
Solution
Correct Answer Is : 1/5
Solution Is :
If p = 99 , then value of p(p2 + 3p + 3) is

a) 10000
b) 99999
c) 100089
d) 999999



Answer
Solution
Correct Answer Is : 999999
Solution Is : P = 99 = (100-1)
p(p2+3p+3) = (100-1) ( (100-1)2 + 3(100-1) + 3 )
= ( 100 - 1) ( 10000 + 1 - 200 + 300 -3 + 3 )
= (100 -1 ) ( 10101)
= 1010100 - 10101 = 999999
When a = 4/3 , then the value of 27 a3 - 108 a2 + 144a -317 is

a) 261
b) -253
c) -245
d) 0



Answer
Solution
Correct Answer Is : -253
Solution Is :
If x = √3 + √2,then the value of (x+1/x) is

a) 2
b) 3
c) 2√2
d) 2√3



Answer
Solution
Correct Answer Is : 2√3
Solution Is : X = √3 + √2
1/x = 1 / (√3+√2 )
Rationalizing , 1/x = 1/(√3+√2) * (√3-√2)/(√3+√2)
= √3-√2 / (3-2) = √3 - √2
x + 1/x = √3 + √2 + √3 - √2 = 2√3
If x-y=2,xy=24,then the value of ( x2 + y2) is

a) 52
b) 25
c) 36
d) 63



Answer
Solution
Correct Answer Is : 52
Solution Is :
If a3 - b3 = 56 and a-b=2,then value of a 2 + b2 will be

b) 48
c) 20
d) 22



Answer
Solution
Correct Answer Is : 20
Solution Is :
