Question

if x=3/2 is zero of the polynomial 2x^2+kx+12 find the value of k

Answer 1

Answer:

why bro.............

Answer 2

Answer: By factor theorem

P ( x ) = 0

p ( 3/2 ) = 2 × ( 3/2 ) ∧2 + k × 3/2 + 12 = 0

= 2 × 9/4 + 3/2k + 12  = 0

= 9/2 + 3/2k + 12 = 0

= 9 + 3k + 12 × 2 = 0

             2

= 33 +  3k = 0

        2

3k = - 33

          2

k = - 33 × 3 = - 99

        2                2
