Find the factored form of each polynomial.

5x^3y − 35x^2y + 50xy = 5xy

3x^3y + 18x^2y − 21xy = 3xy

(x-1)

(x+1)

(x-2)

(x+2)

(x-5)

(x+5)

(x-7)

(x+7)

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
