Solution: Sometimes simplifies to a linear or quadratic equation Solution: Sometimes simplifies to a linear or quadratic equation * To determine the equation type, simplify the equation. Occasionally all variables “cancel out”. If the resulting equation is true (e.g. 5 = 5), then all real numbers are solutions.

Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b. To solve equations that contain rational expressions we can: Simplify the expressions on both sides of the equation (if possible) Cross multiply and set the cross products equal to one another. 3. Solve the equation

example: Solve by completing the square. [Recall that we tried to solve this equation graphically and concluded that there are no real solutions. Thus, we should expect that our solutions will be complex numbers.] SOLUTION: First, we need to find the square of half the coefficient of the linear term (in this case, the coefficient of x):
