Question

State whether the following quadratic equations have two distinct real roots. Justify your answer. x^2-3x +4 = 0 ​

Answer 1

Answer:

if b^2-4ac>0, then it will have 2 distinct real roots... here a=1, b=-3 and c=4.... -(3)^2 - 4*1*4... 9-16.. =-7.. so no, it will not have distinct roots as b^2-4ac<0
