can you please answer #3 and show work

Find the discriminant of the quadratic equation and give the number and type of solutions of the equation. x² + 5x + 2 = 0 x² + 2x + 5 = 0 4x² – 4x + 1 = 0 -2x² + 3x – 7 = 0 9x² + 12x + 4 = 0 5x² – x – 13 = 0 BASKETBALL A basketball player passes the ball to a teammate who catches it 11 ft above the court, just above the rim of the basket, and slam-dunks it through the hoop. (This play is called an “alley-oop.") The first player releases the ball 5 ft above the court with an initial vertical velocity of 21 ft/sec. How long is the ball in the air before being caught, assuming it is caught as it rises? 1
