Question

from a quadratic polynomial whose sum of zero is 8 and product of zeroes 15​

Answer 1

Answer:

x² - 8x + 15

Step-by-step explanation:

Sum of Zeroes (S) = 8

Product of Zeroes (P) = 15

f(x) = x² - (S)x + (P)

f(x) = x² - (S)x + (P)f(x) = x² - 8x + 15 Ans.

Answer 2

The formula for obtaining quadratic polynomial is

x²- (a+b)x + (ab) = 0 (1)

It can also be written as

x²- (b/a)x + c/a = 0 (2)

Here a+b=8 & a×b=15

Putting value of (a+b) & (a×b) in equation(1) we get our required quadratic equation

x²-8x+15 = 0
