Question

2x2+ 5x -4 = 0

• _Value of the Discriminant:
• Number of Solutions:
• Number of x-intercepts:
• Type of Solutions:

Answer 1

Explanation:

value of discriminant:

`5^(2) - 4 (2)(-4)\\=25+32\\=57\\`

As the value of discriminant is larger than zero, so there are 2 distinct solutions.

2 solutions also mean there are 2 x-intercepts.
