    x = -b + - square root b^2 - 4ac/ 2a x = -8 + - square root 8^2 - 4 (1) (-5) / 2 (1) x = -8 + - square root 64 + 20/ 2 x = -8 + - square root 84/ 2 = -8 + - square root 4 * 21/ 2 = -8 + - 2 * square root 21 / 2 x = 2 ( -4 + - square root 21 ) / 2 x = -4 + - square root 21

    Using the completing-the-square method, find the vertex of the function f(x) = 5x2 + 10x + 8 and indicate whether it is a minimum or a maximum and at what point. Maximum at (1, 8) Minimum at (1, 8) Maximum at (–1, 3) Minimum at (–1, 3)
