Question

degree1 of a Polynomial of equation is called-Quadratic, cubic, linear​

Answer 1

degree 1 of a polinomial equation is called linear

Answer 2

Answer:

Those with a degree of 1 are called linear equations.

2x+7=−5

With a degree 2 are called quadratic equations.

4x2+2x+3=0

With a degree of 3 are called cubic.

x3+2x2+x−2=0

There was a universal term applied to all equations with a degree of 4 or above and that's what I forget and that's my question. What are these polynomials / equations called? What's the blanket term?

7y4−2y3+y2−y=121
