Question

If one of the zeros of.
the quadratic
polynomial
2x2 - 8x + k is x-3. find 'k'
Value​

Answer 1

Answer:

Step-by-step explanation:

given quadratic polynomial is ......

2x²-8x-k

given one of the zero is 5/2

2(5/2)²-8(5/2)-k=0

25/2-40/2-k=0

25-40-2k=0

-15-2k=0

k=-15/2

2x²-8x-k

2x²-8x+(15/2)

4x²-16x+15

4x²-10x-6x+15

2x(2x-5) -3(2x-5)

another zeroes are x=3/2

x=5/2
