Question

The zeros of x square - 4 x + 3

Answer 1

The zeros of the polynomial are x = 1 and x = 3

1. If 2 zeros of polynomial x⁴-6x³-26x²+138x-35 are 2±√3, find other zeros.

Answer 2

Step-by-step explanation:

x

2

−3x−x+3

=x(x−3)−1(x−3)

=(x−3)(x−1)

For zeroes of polynomial, p(x)=0

i.e. (x−3)(x−1)=0

or, x=3 or x=1

Let, α=3 and β=1

α+β=

a

−b

αβ=

a

c

Here, a=1b=−4c=3
