Explanation:
Take x out as a factor first to give:
Then factorise the quadratic in the brackets to give the answer above.
Explanation:
Inspection reveals that all three terms have
LHS can be written as
The quadratic in the brackets can be factorized by splitting the middle term
Hence factors are
Explanation:
Take out the common factor of
To factorise the quadratic trinomial, find factors of
Their signs must be different, but there must be more negatives.
This gives:
