Completing the Square: Quadratic Examples & Deriving the Quadratic Formula (page 2 of 2) Solve x2 + 6x + 10 = 0. Apply the same procedure as on the previous page: This is the original equation. x2 + 6x + 10 = 0 Move the loose number over to the other side. x2 + 6x = – 10 Take half of the coefficient on the x-term (that is‚ divide it by two‚ and keeping the sign)‚ and square it. Add this squares value to both sides of the equation. x^2 + 6x + 9 = –10 + 9 Convert the left-hand side to

technology to be developed in agriculture is Aeroponics‚ a method in which a plant’s roots are fed and watered midair. The plants are generally suspended from baskets (similar to those in which strawberries are packaged) at the top of a closed trough or cylinder. With the plants suspended in this manner‚ all essential nourishment can be provided to the roots by spraying them with a nutrient solution. Since the roots are suspended in midair‚ they receive the maximum amount of oxygen possible. This
