Question

Write a quadratic polynomial who's zeros 4+✓3,4-✓3​

Answer 1

Answer:

the factors that control the pulse rate

Answer 2

Answer:

The answer is $x^2-8x+13$

Step-by-step explanation:

Concept: A quadratic polynomial whose zeroes are given is

                   $x^2-(\text{ Sum of zeroes})x+\text{product of zeroes}$

Here given zeroes are $4+\sqrt 3,4-\sqrt 3$

Thus sum $=4+\sqrt 3+4-\sqrt 3=8$

and product $=(4-\sqrt3)(4+\sqrt 3)=4^2-(\sqrt3)^2=16-3=13$

Hence the quadratic polynomial is

                                    $=x^2-8x+13$
