Write down the characteristic equation for the differential equation: y" + 5y' + 4y = 0. The characteristic equation (in the variable lambda ) is. Which one of the following points lies on the line through (-9, 10, -5) in the direction 4i - 2j + 3k (-33,22, -23) (-29,22, -20) (-37,24, -23) (-33,20, -26) The characteristic equation for the differential equation: y " + y' - 20 y = 0, is lambda 2 + lambda - 20 =0. Use this to write down the general solution to the differential equation. The general solution is (using A and B as the unknown constants) y =
