Polynomials [ X ]
1. Find the zeros of the quadratic polynomial and Verify the relationship between its
zeros and
coefficients
a. f(x)
= 4√3
x2 + 5x + 2√3
b. f(x)
=
ab x2 + ( b 2
- ac ) - bc
c. f(x)
=
8u 2 + 8u
d. f(x)
= x2 + 10x + 7
e. f(x)
= x2 - (√3 + 1 ) x + √3
2. If α and β are
the zeros of the
polynomials f(x)
= x2 - 5x + k such
that
α – β = 1 find the
value of k .
3. If α
and β are
the zeros of
the
polynomials f(x)
= x2 - 7x - k
such
that
α –
β = 2 find the
value of k .
4. If α
and β are
the zeros of
the
polynomials f(x)
= a x2 + bx + c .
find
a.
α2 + β2 b.
1 / α2 + 1 / β2
c.
α2 - β2 d. 1 / α2 - 1 / β2
5. Find
all zeros of the polynomials
x3 - 4x2 -7x + 10 it
being Given
that
two if its zeros are
5
and - 2 .
