Which of the following quadratic expressions can be factorised into a product of two binomials using integers?

Advertisement

Answer and explanation

Correct answer: x^2+5x+6

For x^2+5x+6, we need two integers whose product is 6 and sum is 5. The integers 2 and 3 satisfy this, so it factorises as (x+2)(x+3). Exam tip: check the required sum and product for the middle and constant terms.
