Section 2.5 : Quadratic Equations - Part I
For problems 1 – 7 solve the quadratic equation by factoring.
- \({u^2} - 5u - 14 = 0\) Solution
- \({x^2} + 15x = - 50\) Solution
- \({y^2} = 11y - 28\) Solution
- \(19x = 7 - 6{x^2}\) Solution
- \(6{w^2} - w = 5\) Solution
- \({z^2} - 16z + 61 = 2z - 20\) Solution
- \(12{x^2} = 25x\) Solution
For problems 8 & 9 use factoring to solve the equation.
For problems 10 – 12 use factoring to solve the equation.
- \(\displaystyle \frac{{{w^2} - 10}}{{w + 2}} + w - 4 = w - 3\) Solution
- \(\displaystyle \frac{{4z}}{{z + 1}} + \frac{5}{z} = \frac{{6z + 5}}{{{z^2} + z}}\) Solution
- \(\displaystyle x + 1 = \frac{{2x - 7}}{{x + 5}} - \frac{{5x + 8}}{{x + 5}}\) Solution
For problems 13 – 16 use the Square Root Property to solve the equation.
