Please edit my answer for first question. I wrote 'c' instead of 'a'.

For the second question you also missed the power of y.

I am wondering if such answers need to be flagged.

yeswey, can you show us if the missing symbol is within the solution or the final answer?

The final answer is correct but in the second step he missed the power of y. I will post the answer again.

5c^2 +30c + 45

= 5(c^2 + 6c + 9)

= 5(c + 3)^2

= 5(c^2 + 6c + 9)

= 5(c + 3)^2

factor 3y4 - 2y2 - 5 completely **Weegy:** Well, first you have to get a common denominator in your fractions. [ So, your equation becomes:
3y/4 - 4y/4 = 5
Then, we do the subtraction:
-y/4 = 5
Then, let's get rid of the denominator by multiplying both sides by 4:
-y = 20
Which becomes:
y = -20
Unless you've typed something wrong, as far as I can tell, the answer is -20. ] **User:** factor 3y2 +7y + 4 completely **Weegy:** The factors of 3y^2 +7y + 4 are: (3y + 4)(y + 1) **User:** factor 450a2 +242c2 + 660ac completely **Weegy:**
First they are all even so we know we can factor out at least a two and we also need tp rearrange to get in the proper sequence. [ so
2(2225a^2 +121c^2 +330ac) Now changing around
2(225a^2 + 330ac + 121 c^2) The portion inside the parentheses
is a perfect square so the final answer is
2(15a+11c)^2 ] **User:** factor 2a2 + 2b2 - 5ab completely **Weegy:** 2a^2 + 2b^2 - 5ab, when factored is: (a-2b)(2a-b) **User:** factor 128x2 +96xy + 18y2 completely **Weegy:** (128 2) (96 x y) (18 y^2)
= 442368 x y^3 **User:** factor y2x - yx - 20 completely (More)
