Question

If x - 1 is factor of 2x-11x² + bx - 6 then b =​

Answer 1

Answer

GIVEN FUNCTION :–

2 X³ - 11 X² + bx - 6 =0

TO FIND :–

VALUE OF "b"

SOLUTION :–

=》 2 x³ - 11 x² + b x - 6 = 0 , it's one factor is (x - 2) .

● SO , THAT PUT X = 2 in EQUATION –

=》 2 (2)³ - 11(2)² + 2b - 6 = 0

=》 16 - 11 × 4 + 2b - 6 = 0

=》 16 - 44 - 6 + 2b = 0

=》 2b - 34 = 0

=》 b = 17

pls mark me as brainliest

Answer 2

Answer:

15

Step-by-step explanation:

If x-1 is factor of p(x)=2x-11x^2+bx-6 then by factor theorm p(1)=0

2(1)-11(1^2)+b(1)-6=0

2-11+b-6=0

b-15=0

b=15
