Prompt: solve x^2 + 11x + 30 = 0. Show your working Answer: To solve this equation, we can use the quadratic formula: x = (-b +/- sqrt(b^2 - 4ac)) / (2a) Plugging in the values for a, b, and c, we get: x = (-11 +/- sqrt(11^2 - 4130)) / (2*1) x = (-11 +/- sqrt(121 - 120)) / 2 x = (-11 +/- sqrt(1)) / 2 x = (-11 +/- 1) / 2 x = -5 or x = -6 So the solutions to the equation are x = -5 and x = -6. |
