Question

Without finding the discriminant, show that x²+4 has no real zeroes​

Answer 1

Answer:

u can plot a graph

Step-by-step explanation:

suppose y=x²+4

now take different values of x like x= 0,1,2,3 etc

then find respective value of y on the graph i.e for x=0 , y = 4 and  x=1 y = 5 etc again for y= 0 , x = +2,-2
