RADICAL EQUATIONS| WORD PROBLEMS| LEARNING TASK 2 (6-10)

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 6. Find the side of the square if the area is 64m2 . 7. The shorter leg of a right triangle is one half of the longer leg and the hypotenuse is 3 cm. How long is each leg of the triangle? 8. Five times the square root of a number is five. Find the number? 9. The cube root of a number decreased by 3 is zero. Find the number. 10. The square root of the cube root of a number is 2. find the number. Join our Facebook Group : https://www.facebook.com/groups/grade9mathlearnerscalabarzon
