Question

The zeroes of quadratric polynomial x2 - 3 are​

Answer 1

Given :-

The quardratic polynomial is x²-3

To find :-

The zeroes of the quardratic polynomial

Solution :-

Given quardratic polynomial is P(x) = x²-3

We know that

We write P(x) = 0 to get the zeroes of P(x).

Now,

P(x) = 0

=> x²-3 = 0

=> x²-(√3)² = 0

=> (x+√3)(x-√3) = 0

Since, (a+b)(a-b) = a²-b²

Where, a = x and b = √3

=> x+√3 = 0 or x-√3 = 0

=> x = -√3 or x = √3

Answer :-

The zeroes of the quardratic polynomial x²-3 are -√3 and √3
