X^4 + 2x^2 - 24
= (x^2 + 6)(x^2 - 4)
= (x^2 + 6)(x - 2)(x + 2)
x^4 - 9x^2 + 18
= (x^2 - 6)(x^2 - 3)
Answer:
72
Step-by-step explanation:
Stage A has 6 outcomes, then B has 4 and C has 3
Take for example only 1 outcome of A, it will have 4 outcomes of B and each outcome of B will have 3 outcomes.
Then a single outcome of A has a total of 12 outcomes (4*3)
Writing it in a way A, B, C:
1,1,1
1,1,2
1,1,3
1,2,1
1,2,2
1,2,3
1,3,1
1,3,2
1,3,3
1,4,1
1,4,2
1,4,3
This is only taking in consideration 1 outcome of A, A has a total of 6 outcomes.
The total of outcomes in the experiment = 6*12=72
13ab^3(1+3ab) -ANSWER
You're factorising 13ab^3 from the expression - hope this helps:)
Answer: 1/216
Step-by-step explanation:
The ratio is 1/6 so the 7th term is 216 * (1/6) ^ (7 - 1) = 1/216
