Answer:
The other zero is P=2-√3
Step-by-step explanation:
is the given equation,
One of the root is 2+√3 and another root is 0 .
Let p(x)=
Compare p(x) with (linear equation)
a=1, b=-4 & c=1
One zero = 2+√3
Let second zero = p
Sum of zeros = -b/a
Substitute in the form of P+(2+√3)=-(-4)
P=4-(2+√3)
P=2-√3
Product of zero = c/a
(2+√3)p=1
p=1/(2√3)
On rationalizing
P=2-√3/[(2+√3)(2-√3)]
P=2-√3/[22-〖√3〗^2]
P= 2-√3/4-3
P=2-√3
Therefore second zero of p(x)
P=2-√3
