Question

Find a quadratic polynomial, the sum and product of whose zeros are -3 and 2 respectively?

• A. 2x² + 3x + 2
• B. 4x² + 12x + 8
• C. x² - 3x + 2
• D. 4x² - 3x + 2

Answer 1

Answer:

B. 4x² + 12x + 8

Sum of zeros = -3 product of zeros = 2 p(x)=k[x² - sum of zeros × x + product of zeros] p(x) = k[x² - (-3)x + 2] = k[x² + 3x + 2] k is any natural number
