Answer:

x = variable

3 = coefficient

1 = constant

3x^2-4x+1 = algebraic expression

2 = degree

Step-by-step explanation:

variables are typically the letters in equations (usually x and y)

coefficients are the numbers attached to the variables

constants don't have any variables attached

algebraic expressions are the full expression

degrees are the small numbers in the top right corners on either constants, variables or coefficients

Hope this helps!

Solve the equation by completing the

Marizza181 [45]

Answer:

s ≈ - 0.5 , s ≈ 8.5

Step-by-step explanation:

s² - 8s - 4 = 0 ( add 4 to both sides )

s² - 8s = 4

To complete the square

add ( half the coefficient of the s- term )² to both sides

s² + 2(- 4)s + 16 = 4 + 16

(s - 4)² = 20 ( take square root of both sides )

s - 4 = ± $\sqrt{20}$ ( add 4 to both sides )

s = 4 ± $\sqrt{20}$

Then

s = 4 - $\sqrt{20}$ ≈ - 0.5 ( to the nearest tenth ) ← smaller solution

s = 4 + $\sqrt{20}$ ≈ 8.5 ( to the nearest tenth ) ← larger solution
