Answer

Let f(x)=3x

2

+2x

2

−19x+6

Using hit and trial method,

f(1)=3+2−19+6



=0

f(−1)=−3+2+19+6



=0

f(2)=24+8−38+6=0

∴(x−2) is a factor of f(x).

+9x−x−3

=3x(x+3)−1(x+3)

=(3x−1)(x+3)

Hence 3x

Explanation:

Positive thinking, practice, training, knowledge and talking to other people are all useful ways to help improve or boost your confidence levels. Confidence comes from feelings of well-being, acceptance of your body and mind (your self-esteem) and belief in your own ability, skills and experience.
