Solve the quadratic equation by completing the square. first chose the appropriate form and fill in the blanks with the correct numbers. then solve the equation. round your answer to the nearest hundredth. if there’s more than one solution separate them with commas. x^2-4x-3=0

(x - 2)^2 = 7

x = 4.65 or x  = -0.65

Step-by-step explanation:

x^2-4x - 3=0

x^2-4x = 3

x^2-4x  + 4 = 3 + 4

x^2  - 4x + 4 = 7

(x - 2)^2 = 7

x - 2 = +-√7

x = 2 +- √7

x = 4.65 or x  = -0.65

goog may have it for you

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
