Find the values of x of this quadratic equation x^2-4x-5=0

x=−1

Step-by-step explanation: Let's solve your equation step-by-step.

x2−4x−5=0

Step 1: Factor left side of equation.

(x+1)(x−5)=0

Step 2: Set factors equal to 0.

x+1=0 or x−5=0

x=−1 or x=5

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
