Question

find a quadratic polynomial p(y) whose sum and product of zeros are 3 and -2/5
respectively

Answer 1

Answer:

formula is x^2-(a+b)x+ab

Step-by-step explanation:

x^2-(3)x+(-2/5)

x^2-3x-2/5

Answer 2

Answer:

5x^2 + 15x - 2

Step-by-step explanation:

x^2 + (product of zeros)x + (product of zeros) = 0

x^2 + 3x + (-2/5) = 0

multiplying 5 to both sides

5x^2 + 15x + (-2) = 0 * 5

5x^2 + 15x - 2 = 0
