Answer 1

Step-by-step explanation:

In quadratic equations we will learn about ………

● Solving a quadratic equation (factorization method)

● Roots of the quadratic equation.

In polynomials, we studied that a polynomial of degree 1 is called a linear polynomials. 

For example: x - 5, 7x, 3 - 2x are linear polynomials which may be monomials or binomials. 

A polynomial of degree 2 (two) is called a quadratic polynomial. 

For example: 3x², x² + 7 , x² – 3x + 4 are quadratic polynomials which may be monomials, binomials or trinomials.
