Question

if -2 is a zero of the polynomials 3x2+4x+2k , find the value of k.

Answer 1

Hii... ☺

Here's your solution......☺

=================================

P(x) = 3x² + 4x + 2k

P(x) = 0

→ As -2 is a zero of the given polynomial.

Therefore, on putting the value of x as -2 we get,

→ P(-2) = 0
→ 3 × (-2)² + 4 × -2 + 2k = 0
→ 12 - 8 + 2k = 0
→ 4 + 2k = 0
→ 2k = -4
→ k = -4/2
→ k = -2

Hence , value of k = -2

=================================

Hope this helps you...☺
