Question

If one zero of the given quadratic polynomial is 2 then what is the value of k x2+3x+k=0

Answer 1

Given :

• Polynomial is x² + 3x + k

• One of the zeroes is 2

_____________________

To Find :

• Value of k

_____________________

Solution :

Put x = 2 in given equation :

⇒x² + 3x + k = 0

⇒(2)² + 3(2) + k = 0

⇒4 + 6 + k = 0

⇒10 + k = 0

⇒k = -10

➜ Value of k is -10
