Solving equations Section 1.4
Solving equations with radicalsSolve the equation Check for extraneous solutions
Check for extraneous solutions.X=-7 is an extraneous solution. There are no solutions
Solve Check for extraneous solutions!
Solve for x and check for extraneous solutions.X=0 is our solution x=-10 is an extraneous solution
Two Radicals If there are two radicals in the equation, make sure you have one on each side of the equal sign before squaring both sides
Solve for x and check for extraneous solutions.X = -3 is an extraneous solution
Factor the equation with fractional exponents to solve for x
Factor the equation with negative exponents to solve for x
Factor by grouping (2x+3)² + 4(2x+3) + 5 = 0 (2x+3)² + 4(2x+3) = -5
Solving Radical Equations and Inequalities
Remember! For a square root, the index of the radical is 2.
