RADICAL EQUATIONS | WORD PROBLEMS | LEARNING TASK 2

Word Problems involving Radical Equations In solving radical equations, you have to follow the following steps: 1. Write the equation such that the radical containing the unknown is on one side of the equation. 2. Combine similar terms. 3. Raise both sides of the equation to a power same as the index of the radical. The equation should be free of radical to complete the solution. 4. Check if the value or values obtained will make the original equation true. Common problem involving radical is the solution of right triangle applying the Pythagorean Theorem. This theorem is about the relationships among the sides of a right triangle. The theorem states the “sum of the squares of the lengths of the two legs is equal to the square of the length of the hypotenuse. Learning Task 2: Solve the following problems. 1. Twice the square root of a number is 12. Find the number. 2. The square root of a number increased by 9 is 27. find the number. 3. The square root of the sum of twice a number and 3 is 6. Find the number. 4. The perimeter of the square is 25 and the side is . Find the number. 5. The circumference of the circle( C = 2πr) is 24 cm and the radius is Find x and its radius.
