1) Solve x2−4x−5=0 and enter solutions below. 2) Push the "Graph It" Button to see a graph of y=x2−4x−5

Answer 1

Solution:
x^2 - 4x - 5 = 0

Factoring the quadratic equation, we get:
(x - 5)(x + 1) = 0

Setting each factor to zero:
x - 5 = 0
x = 5

x + 1 = 0
x = -1

Therefore, the solutions are x = 5 and x = -1.

Graph of y = x^2 - 4x - 5:
The graph is a parabola that opens upwards. It intersects the x-axis at x = -1 and x = 5.
