There are 10 meatball in the pan. Joey ate one-fifth of the meatball for lunch. He ate 1/2 for dinner. What fraction of the meatball did he eat in all?

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2

Can someone explain to me how to do
