Then the equation of the circle passing through the point \((a, 0)\) and the focus of the parabola, and having its centre on the axis of the parabola is: | 2 | null | \(x^2 + y^2 - 10x + 9 = 0\) | \(x^2 + y^2 - 6x + 5 = 0\) | \(x^2 + y^2 - 4x + 3 = 0\) | \(x^2 + y^2 - 8x + 7 = 0\) | MCQ |
4a48d53e-0787-43ac-aa0c-e9efba9739d7 | If in the expansion of \( (1 + x)^p (1 - x)^q \), the coefficients of \(x\) and \(x^2\) are 1 and -2, respectively, then \(p^2 + q^2\) is equal to: | 2 | null | 18 | 13 | 8 | 20 | MCQ |
