Question

What binomial is a factor of the trinomial x^2-5x+4

Answer 1

Explanation:

Let the equation be

a

⋅

x

2

+

b

⋅

x

+

c

. To factorize multiplication of a and c i.e. ac so that sum of factors, if ac is positive (and difference if ac is negative) is equal to b. Now split b into these two components and factorization will be easy.
