Question

if px = x3-2x2+kx+5 is divided by x-2 the remainder is 11 find k and find its other zeroes and no its answer is not there in brainly so u cant ctrl+x and ctrl+v

Answer 1

Answer:

the value of k in the given problem is 3

Step-by-step explanation:

Remainder theorem

If p(x) is divided by (x-a) then the remainder is p(a)

to find other zeroes the given (x-2) divides exactly then we will find but (x-a) is divided the p(x) leaves the remainder 11

Answer 2

According to the given data

$when\:\: p(x) = 2$

$x^3-2x^2+kx+5=11$

$2^3-2×(2)^2+k(2)+5=11$

$8-8+2k+5=11$

$2k=11-5$

$2k= 6$

$k= 6÷2 = 3$
