Question

determine the nature of roots : x²-4x+4=0​

Answer 1

Answer:

real and equal roots

Step-by-step explanation:

to check the nature of the equation

b^2-4ac should be greater or equal to 0

i.e. it must be positive

here,a=1,b=-4,c=4

(-4)^2-4*1*(4)

=16-16

=o

therefore the equation would have equal and real roots
