Consider the quadratic equation x2 – 10x = –29. Homework Help ✎
Is x = 5 + 2i a solution to the equation? How can you be sure without solving?
Without solving, predict another solution to the equation. Verify your prediction by checking it.
Where does the parabola y = x2 – 10x + 29 intersect the x-axis? Explain.
Substitute the solution into the equation.
Any quadratic equation can be solved using the Quadratic Formula. The "i" part of the solution comes from a negative number inside of the square root. What is in front the the square root in the Quadratic Formula?
Let y = 0 and solve.
