What type of roots will x² - 2x + 1 = 0 have?
x² - 2x + 1 = 0 के roots कैसे होंगे?
Show answer and explanation
Correct Answer
A. दो equal real roots / Two equal real roots
ExplanationStep 1: Find discriminant D = b² - 4ac. Step 2: D = 4 - 4 = 0 so roots are equal real. Step 3: If D is zero remember equal roots.
Step 1: Discriminant D = b² - 4ac निकालें। Step 2: D = 4 - 4 = 0 इसलिए roots equal real होंगे। Step 3: D zero हो तो equal roots याद रखें।
