Question 280547: Solve 25x^2 + 49 = 0 This is what I have: 25x^2 + 49 - 49 = 0 + -49 25x^2 = -49 25x^2/25 = -49/25 x^2 = -1.96 x^2 + 1.96 = 1.96 + - 1.96 x^2 + 1.96 = 0 Therefore a solution cannot be determine. Am I correct or is the solution x^2 + 1.96 = 0? Found 2 solutions by Alan3354, Earlsdon:

After 5 minutes at 20°C application of rated voltage, leakage current is not more than 0,01CV or 1,5mA, whichever is smaller. C: Nominal Capacitance (µF) V: Rated Voltage (V).

May 06, 2015 · That depends on what numbers we are using. This binomial is irreducible (cannot be factored) over the real numbers. If we are working with polynomials over the complex numbers, then this is a difference of squares and can be factored using -49 = (7i)^2, so 25x^2 + 49 = 25x^2 -(-49) =(5x+7i)(5x-7i)
