Solving Radical Equations Calculator is used to calculate the value of the variable of the radical equation. Radical is a symbol used to indicate square root. The 1st step is to isolate the radical value on left/right and rest on the right side and then, square both the sides and simplify.
Example 1: Using solving radical equation calculator to solve the equation
√(2x + 5) + 22 = 30
For the given problem: To bring radical on left side we will subtract both sides by 22
√(2x + 5) + 22 - 22 = 30 -22
√(2x + 5) = 8
Then square both the sides, we get
[√(2x + 5)]2 = 82
2x+5 = 64 ; 2x+5 - 5 = 64 – 5
2x = 59; x = 59/2 = 29.5
Example 1: Using solving radical equation calculator to solve the equation
√(2x + 5) - √(5x+3) = 6
For the given problem: To isolate radical we will subtract both sides by √(5x+3)
√(5x+5) = 6 + √(5x+3)
Square both the sides of the equation
[√(5x+5)]2 = [6 + √(5x+3)]2
5x+5 = 36 + (5x+3) + 2x6√(5x+3)
5x+5 -36 - (5x+3) = 12√(5x+3)
[– 34]2 = [12√(5x+3) ]2
1156 = 144(5x+3) ; 1156 = 720 x+432
720x= 724
X=1.00
