Question

Determine the number that should be added to complete the square of the expression. Then factor the expression.
x^(2) + (1/2)x
Complete the square. What is the resulting perfect square trinomial?

Answer 1

again...divide 1/2 by 2

Answer 2

1/4

Answer 3

now what is (1/4 )^2

Answer 4

.0625

Answer 5

uhh use fraction form

Answer 6

1/16

Answer 7

right so the trinomial is

x^2 + 1/2 x + 1/16

Answer 8

and so how would you factor that?

Answer 9

what do you thinl?

Answer 10

think*

Answer 11

I'm really not sure with fractions

Answer 12

divide 1/2 by 2

Answer 13

1/4

Answer 14

right...so the factor is what?

Answer 15

Uhh, (x+1/4) (x-1/4)? Idk :c

Answer 16

remember a while ago...

you had x^2 - 22x + 121

the factored form was (x - 11)^2

so what would be the factored form for x^2 + 1/2 x + 1/16

Answer 17

(x-1/4)^2?

Answer 18

nope..it's + it was only minus before because -22 was minus...this time 1/2 is + so it's (x+1/2)^2

got it?

Answer 19

Ohh, yeah! thankss.
