Question

The number of points that the quadratic polynomial x^2 +x+2 intersects the x-axis
is :
A)1 ,B)2 ,c)0 ,D)3​

Answer 1

Answer:

option b is the correct answer of the given question

Answer 2

Answer:

Step-by-step explanation

if you draw a graph of that equation

y = x^2 + x + 2

intersect x axis means y = 0

x^2 + x + 2 = 0

if you find by nature of roots

  = b^2 - 4ac

  = 1 -  4(1)(2)

  = -7

if b^2 - 4ac < 0

their are no real roots  

so number of points is 0
