Steps to Factorize a Trinomial of the form x2 + bx + c where b and c are Integers:

Answer»
  • Find all pairs of factors whose product is the last term of the trinomial.
  • From the pairs of factors from step 1, choose a pair of factors whose sum is the coefficient of the middle term of the trinomial.
  • Split the middle term using the pair of factors from step 2 and rewrite the trinomial.
  • Group the terms from step 3 and factorize.
  • Verify the solution.

Factoring a trinomial of the type ax+bx+bx2+c(a≠1) by splitting the middle term

To factorize expressions of the type x2 + bx + c, you will find two numbers a and b such that their sum is equal to the coefficient of the middle term and their product is equal to the last term(constant).

Steps for factoring ax2+bx+c(a≠1) by grouping

  • Find the product (ac), of the coefficient of x2 and the last term.
  • List the factor pairs of ac.
  • Choose a factor pair whose sum is the coefficient of the middle term.
  • Rewrite the polynomial by splitting the middle term.
  • Regroup and factorize.
