Question

What will be the expression of the polynomial whose zeros are -1 and 3 ? *​

Answer 1

Step-by-step explanation:

There are two zeroes so it must be quadratic polynomial .

Z1 = -1

Z2 = 3

the general form of quadratic polynomial,

= x^2 - ( Z1 + Z2)x + Z1 ×Z2

= x^2 - ( -1 + 3 ) x + (-1×3)

= x^2- (2)x -3

= x^2 -2x -3

Answer 2

Answer:

x^2 - 2x - 3.

Step-by-step explanation:

Zeroes = -1 & 3.

So,

sum of zeroes = -1+3 = 2.

product of zeroes = -1*3 = -3.

Now,

general form of. a Quadratic equation = x^2 -(sum of zeroes)x + (product of zeroes)

Quadratic Equation = x^2 - 2x - 3.
