Question 392586
2x^(2)+11x+5

In this problem 5*(1)/(2)=5 and 5+(1)/(2)=11, so insert 5 as the right hand term of one factor and (1)/(2) as the right-hand term of the other factor.
(x5)(x+(1)/(2))

Remove the fraction by multiplying the first term of the factor by the denominator of the second term.
(x+5)(2x+1)
