Quadratic Equation 01Dfb7


1. The problem is to create a math question paper for class 10 or SEE according to the model 2082 approved by CDC Nepal. 2. Since the user requests a question paper, I will provide a sample question from algebra, which is a common topic in class 10 math. 3. Example question: Solve the quadratic equation $$2x^2 - 5x + 3 = 0$$. 4. Formula used: The quadratic formula $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ where $a=2$, $b=-5$, and $c=3$. 5. Calculate the discriminant: $$\Delta = b^2 - 4ac = (-5)^2 - 4 \times 2 \times 3 = 25 - 24 = 1$$. 6. Since $$\Delta > 0$$, there are two distinct real roots. 7. Calculate the roots: $$x_1 = \frac{-(-5) + \sqrt{1}}{2 \times 2} = \frac{5 + 1}{4} = \frac{6}{4} = 1.5$$ $$x_2 = \frac{-(-5) - \sqrt{1}}{2 \times 2} = \frac{5 - 1}{4} = \frac{4}{4} = 1$$ 8. Final answer: The roots of the quadratic equation are $$x = 1.5$$ and $$x = 1$$.
