Answer:
10x^2 (x+2) (x+6)
Step-by-step explanation:
assuming you meant 120 not 1120
10x^4+ 80x^3 + 120x^2
factor out 10 x^2
10x^2 (x^2 +8x+12)
what numbers multiply together to get 12 and add together to get 8
2*6 = 12 2+6 = 8
10x^2 (x+2) (x+6)
B and D are the same answer?????
Answer:
(2a +b)·(13a^2 -5ab +b^2)
Step-by-step explanation:
The factorization of the difference of cubes is a standard form:
(p -q)^3 = (p -q)(p^2 +pq +q^2)
Here, you have ...
so the factorization is ...
(3a -(a -b))·((3a)^2 +(3a)(a -b) +(a -b)^2) . . . . substitute for p and q
= (2a +b)·(9a^2 +3a^2 -3ab +a^2 -2ab +b^2) . . . . simplify a bit
= (2a +b)·(13a^2 -5ab +b^2) . . . . . . collect terms
Answer:
(4,5)
Step-by-step explanation:
-9(3-r)=45
-27+9t=45
9r=45+27
R=72/9
R=8
The answer is 8 not -8
