How do I factor 14x^2-7xy-147y^2
Viefleur [7K]

STEP 1

Equation at the end of step

((14 • (x2)) -  7xy) -  (3•72y2)  

Equation at the end of step 2

 ((2•7x2) -  7xy) -  (3•72y2)

STEP 3

STEP 4

Pulling out like terms

4.1     Pull out like factors :

  14x2 - 7xy - 147y2  =   7 • (2x2 - xy - 21y2)

Trying to factor a multi variable polynomial :

4.2    Factoring    2x2 - xy - 21y2

Try to factor this multi-variable trinomial using trial and error

Found a factorization  :  (2x - 7y)•(x + 3y)

What is the rule for the nth term of the arithmatic sequence given below:
vaieri [72.5K]

Answer:

  an = 5/2 +3/2(n -1)

Step-by-step explanation:

The common difference is ...

  4 -5/2 = 3/2

The general rule is ...

  an = a1 +d(n -1)

For a1 = 5/2 and d = 3/2, the rule for this sequence is ...

  an = 5/2 +3/2(n -1)

___

This can be simplified to ...

  an = 1 +3/2n
