One solution of 2x^2+11x+k=0 is -5. Find the other solution.
:
Here's one way.
Use synthetic division:
________________________
-5 | 2 + 11 + k
..............-10 - 5
.....--------------
..........2...+1 + 0
Which is (2x + 1) is the other solution
:
We know there is no remainder so: k - 5 = 0; k = +5
:
FOIL (x+5)(2x + 1) = 2x^2 + 11x + 5 to check it:
