Question

Show that (x-1) is a factor of the polynomial
f(x) = 2x3 3x² + 7a-6 na​

Answer 1

Answer:

if x-1 factor of given polynomial F (X), then

f(1)=0

now,f(x)=2x³-3x²+7a-6

f(1)=2(1)³-3(1)²+7(1)-6

=2×1-3×1+7-6

=2-3+7-6

=9-9

=0

since,f(1)=0

so,x-1 is a factor of a given polynomial f (x)
