A system of two linear equations in two variables is inconsistent, if their graphs
coincide
intersect only at a point
do not intersect at any point
cut the x-axis
If are two rational expressions, then their product is
On dividing we get
(x - 5) (x - 3)
(x - 5) (x + 3)
(x + 5) (x - 3)
(x + 5) (x + 3)
GCD of (x3 + 1) and x4 - 1 is
x3 - 1
x3 + 1
x + 1
x - 1
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
The lowest form of the rational expression is
LCM of ak, ak + 3, ak + 5 where K N is
ak + 9
ak
ak + 6
ak + 5
The system of equations x - 4y = 8, 3x - 12y = 24
has infinitely many solutions
has no solution
has a unique solution
may or may not have a solution
The square root of 121 x4 y8 z6 (l - m)2 is
11 x2 y4 z4|l - m|
11x4 y4 |z3 (l - m)|
11 x2 y4 z6 |(l - m)|
11x2 y4 |z3 (l - m)|
If is added with , then the new expression is
a2 + ab + b2
a2 - ab + b2
a3 + b3
a3 - b3
