Question 38Asked in BPSC TRE 2.0 (2023) Mathematics Class 9-10 + 8 more papers

The quadratic equation with roots –1 and 4 isमूलों –1 और 4 वाला द्विघात समीकरण है

मूलों –1 और 4 वाला द्विघात समीकरण है
  1. Ax² – 3x – 4 = 0x² – 3x – 4 = 0
  2. Bx² + 3x + 3 = 0x² + 3x + 3 = 0
  3. Cx² – 4x + 1 = 0x² – 4x + 1 = 0
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं

Correct answer: (A) x² – 3x – 4 = 0x² – 3x – 4 = 0

Explanation

Sum of roots = 3 and product = -4, so the equation is x² - 3x - 4 = 0.मूलों का योग 3 और गुणनफल −4 है, अतः समीकरण x² − 3x − 4 = 0 है।
