27and -1000

Step-by-step explanation:

(3)3=27

(10)10=1000

Answer 2

Quadratic Polynomial : x² + 7x - 30 = 0.

Step-by-step explanation:

★ Given that,

• Roots of Quadratic Polynomial are 3 and - 10.

★ To find,

• Quadratic Polynomial.

★ Let,

• α = 3
• β = - 10

➡ Sum of the zeroes : α + β = 3 +(-10) = 3 - 10 = - 7

➡ Product of the zeroes : αβ = 3(-10) = - 30

★ Now,

According to the form of the Quadratic Polynomial

◼ x² - (α + β)x + αβ = 0

• Substitute the zeroes.

➠ x² - (- 7)x + (- 30) = 0

➠ x² + 7x - 30 = 0

Hence, the Quadratic Polynomial is “ x² + 7x - 30 = 0 ”.
