Question

Y=x2+3x+1 has how many real roots?

Answer 1

2

Explanation:

we will find the discriminant of the equation

d = b^2 - 4ac (here, a = 1 , b = 3 , c = 1. from the general formula: ax^2 + bx + c)

d = 9 - 4

d = 5

since d > 0, the roots are real and different

hence, the both the roots of this equation are equal
