Question

for what value of k , in the polynomial p(x) =2x^2 - kx+3x + 19 exactly divived by x =2

Answer 1

Hope it is correct!

Answer 2

Ello!!

Here's your answer

__________________________

Given , p ( x ) = 2 x^2 - kx + 3x + 19 = 0

Now , x = 2

p ( 2 ) = 2 × ( 2 )^2 - k × 2 + 3 × 2 + 19 = 0

=> 2 × 4 - 2k + 6 + 19 = 0

=> - 2k = - 19 - 6 - 8

=> - 2k = - ( 33 )

=> 2k = 33

=> k = 33 / 2

So , the value of k is 33 / 2
