Question

determine whether the expression is a trinomial square
w2 - 4w + 4

Answer 1

-2*-2 = 4
-2 + -2 = -4
= (w-2)^2

Answer 2

dumbcow so the ans. would be yes or no

Answer 3

well i just factored it into a squared binomial, so its a perfect square

Answer 4

Ok can yu help with this one
factor completely 9r2 + 18rc + 8c2

Answer 5

look at factors of 9*8 or 72
12*6 = 72
12 + 6 = 18
(9r +12c)(9r +6c)
=(3r+4c)(3r+2c)

Answer 6

factor completely
2a2 - 28a +98

Answer 7

do the same steps, look at factors of 2*98 or 196

Answer 8

or actually divide everything by 2 first
2(a^2 -14a +49)

Answer 9

look at factors of 49, what adds up to -14

Answer 10

I came up with this answer is it correct
2(a-7)2

Answer 11

yes, good job

Answer 12
