WebSolve the following equation by identifying all of its roots including all real and complex numbers. In your final answer, include the necessary steps and calculations. Hint: Use your knowledge of factoring polynomials. (x2 + 1) (x3 + 2x) (x2 - 64) = 0 x^5+2x^3) (x^3+2x) (x^5-64x^3) (2x^3-128x) x= i, -i, 0, i square root 2, i square root -2, 8, -8 WebFind all the roots, real and complex, of the equation x3 – 2 x2 + 25 x – 50 = 0. x= 2, 5i, –5i. First, factor the equation to get x2 ( x – 2) + 25 ( x – 2) = ( x – 2) ( x2 + 25) = 0. Using the multiplication property of zero, you determine that x – 2 = 0 and x = 2. You also get x2 + 25 = 0 and x2 = –25. Take the square root of each side, and WebThe calculator solution will show work using the quadratic formula to solve the entered equation for real and complex roots.
