LaTeX: \left(3x^2\:-\:1\right)+\left(3x^2\ :-x^3\right)( 3 x 2 − 1 ) + ( 3 x 2 − x 3 )

I wanted to simplify since u didn't specify what u wanted: -x^3 + 6x^2 -1

Step-by-step explanation:

I assume this is what you typed: (3x^2 - 1) + (3x^2 - x^3)

-x^3 + 6x^2 -1

-x³+6x²-1

Step-by-step explanation: Hope it helps

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
