A) the greatest common factor is how to factors something

for this case x is the gcf

x(x^2 - 4) is the answer

B) Cannot be factored there is no common factor.

A) gcf is x

x(x^3/x - 4x/x)
x(x^2 - 4)
x(x^2 - 2^2)
x(x+2)(x-2)

b) 3t^2 -u^2

(3t+u)(3t-u)

y=x^2-8x+6 complete the square to determine the vertex and maximum or minimum value. Determine the number of x-intercepts.

Irina18 [472]

Answer:

Below in bold.

Step-by-step explanation:

y = x^2-8x+6

y = (x - 4)^2 - 16 + 6

y = (x - 4)^2 - 10

So the vertex is at (4, -10)

The coefficient of x^2 of this function is 1 ( positive) so there will be a minimum value.

Minimum value = -10.

x-intercepts:

(x - 4)^2 - 10 = 0

(x - 4)^2 = 10

x - 4 = +/- √10

x = 4 +/- √10

- therefore there are 2 x-intercepts.
