(x+9)^2

Answer 3

it the answer x^2+18+81

Answer 4

(x+9)(x+9) Just FOIL

Answer 5

(y-9)(y-9) FOIL

Answer 6

so it is x^2+81

Answer 7

would the other one be -81 when it starts with a -9

Answer 8

Your answer is still not correct. Your missing one more number in the middle.

Answer 9

so the 18 goes in the middle

Answer 10

The reason for that is because your problems are both minus, if its one minus on plus than the middle would cancel out. Yes the 18 would go in the middle.

Answer 11

both 81 would be positive not negative because the signs are the same.

Answer 12

If the it were like -9 * 9 than it would be -81

Answer 13

so it is the same answer for both of them x^2-18+81

Answer 14

No not for both. Just one little thing change about them in the middle.

Answer 15

one is positive and other is negative

Answer 16

Answer 18

(x+9)^2 x^2+18+81

Answer 25

x - 3)(x + 3)
(Points : 3)

Answer 26

Now this one is just like the previous two but for this one the middle part of it would cancel out because one is positive and the other is negative.

Answer 27

Answer 28

x^2+9

Answer 29

it will not be +9

Answer 30
