Which equation shows y=−12x+4y=−12x+4 in standard form

Recall the definition of a polynomial expression. find two polynomial expressions whose quotient, when simplified,is. use that division problem to determine whether polynomials are closed under division. then describe how theother three operations-addition, subtraction, and multiplication-are different from division of polynomials.

Find the quotient. 50a2 – 98b2 -5a +7b

Can someone me i’m confused. will give brainliest and a whole bunch of points
