Answer:
x = 5 and x = -1
Step-by-step explanation: x^2 -4x - 5 = 0
consider the form x^2+bx+c. Find a pair of integers whose product is C and whose sum is b. In this case c is -5 and b is -4
if any individual factor on the left side of the equation is equal to 0 the entire expression will be equal to 0
x-5 = 0 x = 5
x+1 = 0 x = -1
