Quadratic Equation:


An equation, which contains the square of the unknown (variable) quantity, but no higher power, is called a ………..
a) Linear equation    
b) Quadratic equation
c) completing square          
d) cubic equation


A second degree equation in one variable x of the form:
a)ax3+bx+c = 0    
b) ax4+bx
c) ax2+bx+c = 0                    
d)ax+b


If b=0 in a quadratic equation ax2+bx+c=0, then this equation is called
a)Quadratic                                          
b)pure quadratic
c) standard form                  
d) None of these


By solving the equation x2-3x-4=0 by completing square, then the roots of equation will be:
a){-1,4}                                  
b) {1,4}                      
c) {-4,1}                                 
d) {0,4}
