MCQ
$4x^2- 20x + 25 = 0$ have :
- AReal roots
- BNo Real roots
- ✓Real and Equal roots
- DReal and Distinct roots
✓
Answer
Correct option: C.
Real and Equal roots
$D = b^2- 4ac$
$D = (-20)^2- 4 \times 4 \times 25$
$D = 400 - 400$
$D = 0$.
Real and equal roots.
$D = (-20)^2- 4 \times 4 \times 25$
$D = 400 - 400$
$D = 0$.
