To factor ax^2+bx+c:
1st multiply ac=26;
2nd find pair of numbers whose product is ac, and sum is b:
1+26=27;
3rd rewrite middle term accordingly: 2x^2+1x+26x+13.
4th factor by grouping: x(2x+1)+13(2x+1) Note: Make sure stuff in parentheses is the same for both terms.
5th factor common term: (2x+1)(x+13)
