What is the discriminant of the polynomial below? 
2x^2 + 3x - 7 
A. -5 
B. -47 
C. 23 
D. 65 
                                             
                                          
                                          
                                        
											 
											Answer:
2x^2 + 3x - 7 (a= 2 , b= 3 , c= -7)
discriminant= b^2 - 4ac
= (3)^2 - 4(2)(-7)
= 9 + 56 = 65
The answer is D. 65
Hope this helps :)
