Section 2.7 : Quadratic Equations : A Summary

For problems 1 – 4 use the discriminant to determine the type of roots for the equation. Do not find any roots.

1. \(169{x^2} - 182x + 49 = 0\) Solution
2. \({x^2} + 28x + 61 = 0\) Solution
3. \(49{x^2} - 126x + 102 = 0\) Solution
4. \(9{x^2} + 151 = 0\) Solution
