Question

A quadratic polynomial, whose zeroes are -4 and -5 is ans. me fast then I will mark ur ans. as brainliest. ​

Answer 1

Answer:

Requiredanswer:

GiveN:

The zeroes of the quadratic polynomial are -4 and -5.

To FinD:

Find the quadratic polynomial?

Step-by-step Explanation:

Let the zeroes of the quadratic polynomial be:

α = -4,

β = -5

Then,

α + β = -4 + ( -5) = -9

αβ = -4 × (-5) = 20

That means,

Sum of zeroes = α + β = -9

Product of zeroes = αβ = 20

Then, the quadratic polynomial

= x² - (sum of zeroes)x + product of zeroes

= x² - (-9)x + (20)

= x² + 9x + 20

Hence,

The required quadratic polynomial is x² + 9x + 20.
