how to split middle term?
Asked by nachiket arora | 28th Nov, 2010, 12:00: AM
Following is the method of splitting the middle term of the quadratic equation ax2+bx+c=0, where a ≠ 0.
- Form the product “ac”
- Find a pair of numbers b1 and b2 whose product is “ac” and whose sum is “b” (if you can’t find such numbers, it can’t be factored).
- Split the middle term using b1 and b2 – that is express the term bx as b1x + b2x. Now factor by grouping pairs of terms.
We hope that clarifies your query.
