Answer 1

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.
