Question

1) Solve 2x^2 - 5x - 3 = 0 and enter solutions below.

2) Push the "Graph It" Button to see a graph of y = 2x^2 - 5x - 3

Solution 1:

Solution 2:

Answer 1

Solution 1: -1/2

Solution 2: 3

Explanation:

2x^2 - 5x - 3 = 0
2x^2 - 6x + x - 3 = 0
2x(x - 3) + (x-3) = 0
(2x + 1)(x-3) = 0

2x + 1 = 0
x = -1/2

x - 3 = 0
x = 3
