Question

find the quadratic polynomial whose zeroes are - 5 ,- 7 ​

Answer 1

Answer:

plss follow me.

Step-by-step explanation:

given , the zeroes of the polynomial: 5 & -7

so,

$x2 – (α+β)x + (αβ) = 0$

now alpha = 5

& beta = -7

x² - [5+(-7)]x +(5×-7)=0

= x²+4x-35=0

thus the quadratic equation formed from the zeroes of its is

x²+4x-35=0.
