Solution:

  • 6 + x - x^2
  • = 6 + 3x - 2x - x^2
  • = 3(2 + x) - x(2 + x)
  • = (2 + x)(3 - x)

Answer:

(2 + x)(3 - x)

To factorise a quadratic we first need to think of factors of the number term (The 6).

Factors of 6 are 1 & 6 and 2 & 3.

What combination of addition or subtraction of these factor pairs will produce the second number (which is positive 1x)

3 minus 2 will give us 1, so we will use this pair

Throw up your brackets with the x's and the number pair we chose

(x 2) (x 3)

We chose 3 minus 2

So in our brackets we will put positive 3, negative 2

(x - 2) (x + 3)
