(x+0.5)^2=0.64 solve the equation for x

Hi,

= (x + 1/2) = 8/10

= () = 8/10

= 20x + 10 = 16

= 20x = 6

= x = 6/20

= x = 3/10

x => 0,3

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
