On dividing we get
(x - 5) (x - 3)
(x - 5) (x + 3)
(x + 5) (x - 3)
(x + 5) (x + 3)
If ax2 + bx + c = 0 has equal roots, then c is equal to
The square root of x2 + y2 + z2 - 2xy + 2yz - 2zx is
|x + y - z|
|x - y + z|
|x + y + z|
|x - y - z|
If the system 6x - 2y = 3, kx - y = 2 has a unique solution then
k = 3
k ≠ 3
k = 4
k ≠ 4
If x2 + 5kx + 16 = 0 has no real roots, then
A quadratic equation whose one root is 3 is
x2 - 6x - 5 = 0
x2 + 6x - 5 = 0
x2 - 5x - 6 = 0
x2 - 5x + 6 = 0
If is added with , then the new expression is
a2 + ab + b2
a2 - ab + b2
a3 + b3
a3 - b3
The sum of two zeroes of the polynomial f(x) = 2x2 + (p + 3) x + 5 is zero, then the value of p is
3
4
-3
-4
If one zero of the polynomial p(x) = (k+4) x2 + 13x + 3k is reciprocal of the other, then k is equal to
2
5
The square root of 49(x2 - 2xy + y2)2 is
7|x - y|
7(x + y) (x - y)
