    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) for 2nd question of u
