Completely factor.
x^4 + 3x^3 + 4x^2 + 12x = 0​

x⁴ + 3x³ + 4x² + 12x = 0

<=> x³(x + 3) + 4x(x + 3) = 0

<=> (x³ + 4x)(x + 3) = 0

<=> x(x² + 4)(x + 3) = 0

f . i can go whenever i feel like it bc it is confidential meaning only i would know how much i deposited besides the bank and they wouldnt care bc when you make a deposit you are using their services which means they are using there competition and gaining more customers

and if they dont well then thats less customers for them in a less profitable way

plz mark brainliest
