Question

Write the quadratic polynomial whose zeros are - 3 and 4

Answer 1

Answer:

Step-by-step explanation:

Given zeroes of the polynomial are 3 and 4

Sum of Zeroes =3+4=7

Product of zeroes=3×4=12

Polynomial=x^2-(sum of zeroes)x+(product of zeroes)

So the quadratic polynomial is =x^2-7x+12

Hope it helps...

Answer 2

We let two zeroes ----> A & B

A+B = -3

AB = 4

Using formula,

K[x^2 - (A+B)x + (AB)]

Now, we put values

K[x^2 - (-3)x + (4)]

K[x^2 + 3x + 4]

Where K is constant,

And x^2 + 3x + 4 is quadratic equation.
