Question

Find a quadratic polynomial whose zeroes are -1 and -2​

Answer 1

(x + 1)(x + 2)

x² + 2x + x + 2

x² + 3x + 2

Answer 2

Answer:

Step-by-step explanation:

zeroes are -1 and -2

therefore,

      alpha (α) -1

       beta (β) = -2

α + β = -1 + -2 = -3

αβ = (-1)(-2) = 2

we know, x² - (α +β)x + (αβ)

                x² + 3x - 2 is the final answer
