Factorise: x2 − 10x + 25
गुणनखंड (Factor) कीजिए: x2 − 10x + 25
Answer और ExplanationAnswer and explanation
Answer: (A) (x − 5)2
25 = 52 है, और बीच का पद (Term) 10x = 2 × x × 5 है, − चिह्न के साथ।
इसलिए x2 − 10x + 25 = x2 − 2 × x × 5 + 52 = (x − 5)2
✓
उत्तर (x − 5)2 है।
25 = 52, and the middle term is 10x = 2 × x × 5, with a − sign.
So x2 − 10x + 25 = x2 − 2 × x × 5 + 52 = (x − 5)2
✓
The answer is (x − 5)2.
