it doesn't matter how many zeros you have after the .6 it's still 6 tenths. It can have a hundred zeros it will still be just .6 = 6/10 = 6 tenths

Hope that helps you. :-)

How do you factor this trinomial 4a^2-4a+1

ElenaW [278]

Answer:

$(2a-1)(2a-1)$

Step-by-step explanation:

To write the factored form, multiply a*c from the standard form $ax^2+bx+c$ . Here it is 4*1 = 4.

Then find factors of 4 that add to b=-4.

4: 1,2,4

-2+-2 = -4

Split the middle term into -2x+-2x and factor by grouping.

$4a^2-2a+-2a+1\\(4a^2-2a)+(-2a+1)\\2a(2a-1)-1(2a-1)\\(2a-1)(2a-1)$

What fomula can be used to describe the sequence? -2/3,-4,-24,-144

Lunna [17]

This is a geometric sequence with n th term formula

$a_{n}$ = $a_{1}$ $(r)^{n-1}$

where r is the common ratio and $a_{1}$ the first term

here $a_{1}$ = - $\frac{2}{3}$ and

r = $\frac{-144}{-24}$ = $\frac{-24}{-4}$ = 6

$a_{n}$ = - $\frac{2}{3}$ $(6)^{n-1}$

or in terms of x

f(x) = - $\frac{2}{3}$ $(6)^{x-1}$
