Question

Check whether 2x +1 is a factor of 6x 3 +13x 2 +x – 2

Answer 1

Step-by-step explanation:

(2x+1)=0

2x=-1

x= -1/2

put the value of x in equation

6*(-1/2)³+13*(-1/2)²+(-1/2)-2

-6*1/8-13*1/4-1/2-2

= -3/4+13/4-1/2-2

-3/4+13/4-2/4-8/4

= (-3+13-2-8)/4

=(-13+13)/4

=0/4

=0

hence (2x+1) is a factor of 6x³+13x²+x-2
