Question

show that x-1 is a factor of polynomial f(x)= 2xcube-3xsquare+7x-6

Answer 1

HEY THERE!!!

GIVEN:-

Polynomial:- 2x³-3x²+7x-6

Factor of Polynomial:- x-1

f(x)=x-1

f(0)=x-1=1

•°• x=1

Now,

Substitute the Value of x in Given polynomial;

2x³-3x²+7x-6

f(x)=2x³-3x²+7x-6

f(1)=2(1)³-3(1)²+7(1)-6

f(1)=2×1 -3 +7-6

f(1)=2-3+1

f(1)=-1+1

f=0

Hence, It is Factor of this Polynomial 2x³-3x²+7x-6.
