Question

The graph of a polynomial y=4-x^2 Is given alongside. What are the zeros of the polynomial

Answer 1

Answer:

+2 and -2

Step-by-step explanation:

Given a quadratic polynomial such that,

y = 4 - x^2

To find the zeroes of the polynomial.

We need to convert it into an equation.

For this, equate rhe Polynomial to zero.

Therefore, we will get,

=> y = 0

=> 4 - x^2 = 0

So, it's the required quadratic equation.

Now, finding the zeroes, we get,

=> 4 - x^2 = 0

=> 2^2 - x^2 = 0

But, we know that,

• a^2 - b^2 = (a+b)(a-b)

Therefore, we will get,

=> (2+x)(2-x) = 0

Now, we have two cases.

CASE I

=> 2 + x = 0

=> x = -2

CASE II

=> 2 - x = 0

=> x = 2

Hence, the zeroes are +2 and -2.
