5x + 2
x^2 + 4x - 12

5x²+37x+14  (or)  (5x+2)(x+7)

Step-by-step explanation:

X²+4x-12 factors as (x+6)(x-2)

In order for the two sides of the equation to be equal, you have to multiply the top by (x+7) since the bottom is.

(5x+2)(x+7)=5x²+37x+14

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,
