Question

if z is a zero of the polynomial x2-3x to then the value o​

Answer 1

Step-by-step explanation:

The value of k is -10

Step-by-step explanation:

Given : Quadratic polynomial

One of the root is 2

To find : The value of k

Solution :

Let the given quadratic polynomial be

Given one of the zero of the quadratic polynomial is 2.

Hence f(2) = 0

Put x = 2 in f(x), we get

Therefore, The value of k is -10.

Answer 2

Answer:

The zeros of polynomial p(x)=x

2

−3x+2 can be given y p(x)=0

⟹x

2

−3x+2=0

x

2

−2x−x+2=0

x(x−2)−1(x−2)=0

(x−1)(x−2)=0

x=1,2
