Answer:
If α and β are zeroes of a quadratic polynomial x2-5, then form a quadratic polynomial whose zeroes are 1+α and 1+β
Step-by-step explanation:
ax²+bx= 0
(a and b are the roots of equation)
sum of roots = a+b = -b/a
product of roots= a.b =c/a
now equation is
x²-5---->.
x²+0x -5
a=1, b= 0, c=-5
sum of roots = 1+a. + 1+ b
= 2+a+b
= 2
product of roots =a.b
=(1+a).(1+b)
= 1+a+b+a.b= 1+0-5. = -4
hence equation is
f(x) = ax² - ( sum of roots ) + product of roots
f(x) = x² - 2x -4
hope it helps
