Factor each equation into two linear binomials and set those binomial equal to zero separately and solve for x.
Answer:
The turning point of a parabola is the vertex
Vertex form of a quadratic equation: 
(where (h, k) is the vertex and a is the coefficient of the variable x²)
Given:
- vertex = (-1, 3)
Therefore, a = 1
Substituting a = 1 and the given vertex into the equation:
Therefore, a = 2 and b = 4

Step-by-step explanation:
Remark
It's not 82.
You have to take the 62% off and then follow it with 20% from the new price.
Solution
62%
If you get a reduction of 62%, it means that you pay 100% - 62% = 38% of the marked price of $49.95.
38% price =49.95 * 62/100
38% price = 3096.9 / 100
38% price = $30.97
20% Reduction
20% more means that you pay 100% - 20% = 80%
20% more reduction = 30.97 * 80/100
20% more reduction = 2478/100
20% more reduction = 24.78
Conclusion.
Your final price before taxes is $24.78
