ЧЬ^2 -ЧЬ +1
How do u factor is

(2b-1)(2b-1)

Step-by-step explanation:

Check your work

2b x 2b = 4b^2

2b x -1 = -2b

-1 x 2b = -2b

-1 x -1 = 1

Simplify

4b^2-4b+1

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

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
