Question

Find a quadratic polynomial , the sum and product of whoes zeroes are -3 and 5 respectively .

plz help me !!!

Answer 1

$x {}^{2} + 3x + 5$
if u like please make me BRAINLIEST
x2 - (sum of zeroes)x + product of zeroes
now put the value of sum of zeroes and product of zeroes

Answer 2

Hope u like my process
=====================
Let one of the root be a

So, the other root be b

According to the problem
---------------------------------------
$= > a + b = - 3.......(1) \\ \\ = > ab = 5$
Now.,
=-=-=-
For a quadratic equation,

x² - (sum of the zeroes)x +(product of zeroes) =0

So,

=> x² - (a+b) + ab =0

or, x² - (-3)x +5 =0

or, x² + 3x + 5 = 0___(answer)
