Question

if x-2 is a factor of 2x²-11x²+bx-6 then the value of b is
a.16
b.18
c.17.
d.19

Answer 1

hlo dear

firstly i want to tell u that ur que is wrong

the correct que is :- 2x³-11x²+bx-6

then the solution is

Given (x-2) is the factor of the given equation

then

x-2 = 0

x=2

then

f(x) = 2x³-11x²+bx-6

then putting the value of x

we get

f(2) = 2(2)³-11(2)²+b(2)-6

here f(2) = 0 bec {x-2 is the factor of given equation}

0=16-44+2b-6

50-16=2b

b = 34/2

b = 17

then (c) is the correct option

mark my ans as brainlliest

thank u so much
