Solution Hints

Problems 2, 3, 4, 5 :
Combine like terms and either factor the expression or use the quadratic formula. The solution set may be one real number, two real numbers, or two complex numbers.

Problems 6, 13, 14 :
The system represents the intersection of a parabola and line. Use subsitution to create a quadratic equation in one variable, solve it, then plug your solution(s) into one of the equations to find the value(s) of the other variable. If either x or y is a complex number then the parabola and line have no intersection point(s). The solution set may be one coordinate pair, two coordinate pairs, or no solution.

Problems 7, 8 :
Expand the left side and combine like terms, then either factor or use the quadratic formula. The solution set may be one real number, two real numbers, or two complex numbers.

Problems 10, 19 :
Multiply both sides of the equation by x, then either factor or use the quadratic formula. The solution set may be one real number, two real numbers, or two complex numbers.

Problems 11, 12, 16 :
When the radical is by itself on one side of the equation, square both sides. Then combine like terms and either factor or use the quadratic formula. After you solve for x, plug the value(s) back into the original equation to make sure it is a consistent solution. If x is a complex number or the quantity under the radical is negative, then x is not a solution. The solution set may be one real number, two real numbers, or no solution.

Problems 9, 15, 17, 18 :
Cross multiply, then combine like terms. Either factor the equation or use the quadratic formula to solve for x. Plug your answer(s) back into the original fractions to make sure the denominator is defined (non-zero). The solution set may be one real number, two real numbers, two complex numbers, or no solution.

Problems 20 :
Multiply both sides of the equation by x2, then either factor or use the quadratic formula. The solution set may be one real number, two real numbers, or two complex numbers.
