Question

if 2, is a zero of the polynomial 2x square-3x +k find the value of k

Answer 1

Answer:

k = (-2)

Step-by-step explanation:

2 is zero of polynomial p(x)

therefore p(2) = 0

p(x) 2x²-3x+k = 0

p(2) 2(2)²-3(2)+k = 0 (Substituting 2 in place of x)

p(2) 8-6+k = 0

p(2) 2+k = 0

therefore k=(-2)

Answer 2

Step-by-step explanation:

If 2 is a zero of the polynomial of 2x²-3x+k , then find the value of k

( put 2 in place of x )

2 × (2²) -3×2+k =0

2×4 -6 +k =0

8-6 +k =0

2 +k =0

k= -2
