l (4x+10)^2=400

Answer
x = ±2.5

↓Steps Explained:↓



Solve the following equation

(4x+10)^2=400

Solve for x

(4x+10)2 = 400

Take the square root of each side:

(4x+10)2 = √400

4x+10 = 20

Subtract - 10 from both sides of the equation

4x+10 - 10 = 20 - 10

4x=10

Divide each side of the equation by 4

4x
4
  
10
4

Build our solution:

x = ±2.5

Final Answer

x = ±2.5
