User: How Do I Solve The Math Equation:

Weegy: Method 1. Factorise as the difference of two squares: (y sqrt(5) - 2)(y sqrt(5) + 2) = 0 Equate each factor in turn to zero: y sqrt(5) = 2 y = 2 sqrt(5) / 5 or y sqrt(5) = - 2 y = - 2 sqrt(5) / 5. Method 2. Add 4: 5y^2 = 4 Divide by 5: y^2 = 4 [ / 5 Take square root: y = +/- 2 sqrt(5) / 5.
