1. Which of the following are solutions to x2 - 4x - 5 = 0? List all correct answers
a. -5
c. -1
b. 5
d. 1

c. -1

b. 5

Step-by-step explanation:

x^2 - 4x - 5 = 0

Factor

What two numbers multiply to -5 and add to -1

-5*1 = -5

-5+1 = -4

(x-5) (x+1) =0

Using the zero product property

x-5 =0      x+1 =0

x=5            x=-1

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
