Q. Find the roots of the equation:\newliney=5x2+4x19y = 5x^2 + 4x - 19
  1. Identify Coefficients: Step Title: Identify the Coefficients\newlineConcise Step Description: Identify the coefficients of the quadratic equation, which are the numbers in front of the variables. In this case, the coefficients are 55, 44, and 19-19.\newlineStep Calculation: Coefficients are 55, 44, 19-19\newlineStep Output: Coefficients: 55, 44, 19-19
  2. Calculate Discriminant: Step Title: Calculate the Discriminant\newlineConcise Step Description: Calculate the discriminant of the quadratic equation using the formula D=b24acD = b^2 - 4ac, where aa, bb, and cc are the coefficients of the equation.\newlineStep Calculation: D=424(5)(19)=16+380=396D = 4^2 - 4(5)(-19) = 16 + 380 = 396\newlineStep Output: Discriminant: 396396
  3. Check Discriminant: Step Title: Check the Discriminant\newlineConcise Step Description: Check the discriminant to determine the nature of the roots. If the discriminant is positive, there are two real and distinct roots.\newlineStep Calculation: Since 396396 is positive, there are two real and distinct roots.\newlineStep Output: Nature of roots: Two real and distinct roots
  4. Find Roots: Step Title: Find the Roots\newlineConcise Step Description: Use the quadratic formula to find the roots of the equation. The quadratic formula is x=b±D2ax = \frac{-b \pm \sqrt{D}}{2a}.\newlineStep Calculation: x=4±3962×5=4±29910x = \frac{-4 \pm \sqrt{396}}{2 \times 5} = \frac{-4 \pm 2\sqrt{99}}{10}\newlineStep Output: Roots: x=4+29910x = \frac{-4 + 2\sqrt{99}}{10} and x=429910x = \frac{-4 - 2\sqrt{99}}{10}
