If is added with , then the new expression is
a2 + ab + b2
a2 - ab + b2
a3 + b3
a3 - b3
The LCM of x3 - a3 and (x - a)2 is
(x3 - a3) (x + a)
(x3 - a3) (x - a)2
(x - a)2 (x2 + ax + a2)
(x + a)2 (x2 + ax + a2)
If x2 + 5kx + 16 = 0 has no real roots, then
The lowest form of the rational expression is
The square root of 49(x2 - 2xy + y2)2 is
7|x - y|
7(x + y) (x - y)
7 (x + y)2
7 (x - y)2
The GCD of x2 - 2xy + y2 and x4 - y4 is
1
x + y
x - y
x2 - y2
The remainder when x2 - 2x + 7 is divided by x + 4 is
28
29
30
31
If are two rational expressions, then their product is
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
The quotient when x3 - 5x2 + 7x - 4 is divided by x - 1 is
x2 + 4x + 3
x2 - 4x + 3
x2 - 4x - 3
x2 + 4x - 3
