Answer:
B.) 5, -1
Step-by-step explanation:
Formula:
ax^2+bx=c
Shift the equation and set it equal to 0 by subtracting c.
ax^2+bx+c=0
So, in this case:
x^2-4x=5
Shift the equation:
x^2-4x-5=0
a= 1
b= -4
c= -5
Now, to figure out the zeros of an equation like this:
You need to find two numbers that multiply to c (-5), but also add to b (-4).
These numbers are 5 and -1
So, the zeros of the equation are 5 and -1.
