Question 1: If one root of x2 + px + 12 = 0 is 4, while the equation x2 + px + q = 0 has equal roots, then the value of q is
(a) 49/4
(b) 4/49
(c) 4
(d) 1/4

Answers and Explanations

Answer : (a)

The given equation is x2 + px +12 = 0. Since x = 4 is a root of this equation, so it will satisfy it.

Hence, we have 16 + 4p + 12 = 0 => 4p = – 28 => p = -7.

Hence the second equation becomes x2 – 7x + q = 0.

Now the roots of this equation are equal, so its discriminant = (b2 – 4ac) will be 0.

We get:

( -7)2 – 4q = 0 => 4q = 49 => q = 49/4.

Question 2: For the given pair (x, y) of positive integers, such that 4x – 17y = 1 and x < 1,000, how many integer values of y satisfy the given conditions?
(a) 55
(b) 56
(c) 57
(d) 58
