Question

if alpha and beta are the zeros of the polynomial 2 x square - 7 x + 3 find the sum of reciprocal of these zeros​

Answer 1

What is a polynomial?

A polynomial is an algebraic expression having the degree of it's variables as a whole number.

For example - 2, x , x+4, 4x³ etc.

The classification of polynomials can be done in two ways :

• On the basis of degree :

★ Linear Polynomial - The polynomial having the degree = 1

★ Quadratic Polynomial - The polynomial having the degree = 2

★ Cubic Polynomial - The polynomial having the degree = 3

• On the basis of terms :

★Monomial : The polynomial having a single term only.

★ Binomial : The polynomial having two terms.

★ Trinomial : The polynomial having 3 terms.

Answer 2

Answer:

7/3

Step-by-step explanation:

2x^2- 7x + 3

2x^2- 6x -x + 3(splitting the middle term)

2x(x-3) -1(x-3)

(x-3)(2x-1)

• zeroes are 3,1/2

• reciprocals=1/3,2

• sum=1/3+2

=(1+6)/3

=7/3
