Use the quadratic formula to solve each equation. If necessary, round to the nearest hundredth.3. 6g2 + g 2 = 04. a2 + 7a 9 = 0

Find the number of solutions of each equation.5. 2h2 3h + 2 = 06. b2 + 5b 3 = 0 Find the value of n such that each expression is a perfect square trinomial.7. a2 + 18a + n8. t2 22t + n9. b2 + 20b + nSolve each equation. If necessary, round to the nearest hundredth.

10. d2 d = 3011. 15x2 23x + 4 = 0
