Question

I can make packets of 6 sweets or 8 sweets or 10 sweets. What least number of sweets must I have so that I can put them in any of the grouping mentioned above without leaving any sweet?​

Answer 1

Answer:

2

Step-by-step explanation:

If 1 is the zero of the polynomial f(x)=a  

2

x  

2

−3ax+3x−1

Then, f(x)=0

=>a  

2

(1)  

2

−3a(1)+3(1)−1=0

=>a  

2

−3a+3−1=0

=>a  

2

−3a+2=0

=>a  

2

−2a−a+2=0

=>a(a−2)−1(a−2)=0

=>(a−2)(a−1)=0

a=2
