1) solve by using the perfect squares method. x2 + 8x + 16 = 0
2) solve. x2 β 5x β 6 = 0
3) what value should be added to the expression to create a perfect square? x2 β 20x
4) solve. x2 + 8x β 8 = 0
5) solve: 2x2 + 12x = 0
6) solve each problem by using the quadratic formula. write solutions in simplest radical form. 2x2 β 2x β 1 = 0
7) calculate the discriminant. x2 β x + 2 = 0
8) calculate the discriminant and use it to determine how many real-number roots the equation has. 3x2 β 6x + 1 = 0
9) without drawing the graph of the equation, determine how many points the parabola has in common with the x-axis and whether its vertex lies above, on, or below the x-axis. y = 2x2 + x β 3
10) without drawing the graph of the equation, determine how many points the parabola has in common with the x-axis and whether its vertex lies above, on, or below the x-axis. y = x2 β 12x + 12
