You can put this solution on YOUR website! Factor:
1. 3r^7 - 192r^4
= 3r^4[r^3-64]
= 3r^4(r-4)(r^2+4r+16)
================================
Factor by grouping:
2. 3x^3- 27x^2 - 4x + 36
3x^2(x-9) -4(x-9)
=(x-9)(3x^2-4)
================================
Factor:
3. a^3 – 49a^2 – 9a + 441
= a^2(a-49)-9(a-49)
= (a-49)(a-3)(a+3)
================================
Multiply:
4. (x^4 +x^3)(x^4+ x^3- x^2)
Multiply each term of the 1st factor times
each term of the 2nd factor.
The add the like terms.
===================================
Add:
5. (9 + 5x +6x^2 + 8x^3) + (4 – 5x +6x^2 – 8x^3)
Add the like terms:
= 13 + 0 +12x^2 + 0
----
= 12x^2+13
===============

On the webpage where you submit your question, there is a block of text entitled "Read these RULES before submitting your question"
Here is one of those rules: "One problem per submission."
So my question to you is: Did you not read the rules even though the page says to read them, or did you read them but believe that you are somehow special or more important than anyone else such that the rules don't apply to you?

My calculator said it, I believe it, that settles it
