Question

2² - 4x + 4=0 has equal roots. true or false​

Answer 1

Answer:

False

Step-by-step explanation:

Given polynomial,

2x² - 4x + 4

It is of the form ax² + bx + c

a = 2,b = -4,c = 4

Discriminant, D = b² - 4ac

D = (-4)² - 4 (2)(4)

D = 16 - 32

D = -16 < 0

It has imaginary roots.

If D = 0, real and equal roots.

If D > 0 , real and unequal roots

If D < 0, no real roots
