Question

How do you solve `5n^2+14=17n`?

Answer 1

Solve quadratic equation `f(n) = 5n^2 - 17n + 14 = 0`

Explanation:

I use the new Transforming Method (Google, Yahoo Search)
Transformed equation: `n^2 - 17n + 70 = 0.` Roots have same sign.
Factor pairs of (70) ->....(5, 14)(7, 10). This sum = -b.
The 2 real roots are: `7/5 and 10/5 = 2`
