-3x² + 6x +9 =
factor

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

Step-by-step explanation:

First you find a number that is able to factor out of -3, 6, and 9

In this case it's 3

and since a is a negative, factor out -3

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

That would be your final answer since you can't factor anything anymore.

Hope that helps!

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

im not sure of the names, but the answer is 48
