Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 143x^2-174x+1392=0. To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=143, b=-174 and c=1392. Then substitute the values of the coefficients of the equation in the quadratic formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}. To obtain the two solutions, divide the equation in two equations, one when \pm is positive (+), and another when \pm is negative (-). Calculate the power \sqrt{-765948} using complex numbers.
