Carry out the following steps to find the factors of the following:
3.1.1 2x²+10x+8
3.1.2 3x²-12x+9
3.1.3 5x2 - 25x - 30

REMEMBER
If the common factor which is taken out, is a
monomial, the number of terms left between
the brackets will be the same number with
which
you started.
3.1.4 2x2+2x-40

Step 1: Is the coefficient of x2, the first term in the trinomial, one, in 3.1.1-
3.1.4?
Step 2: Rewrite the expression in 3.1.1 - 3.1.4 in its factors such that the
coefficient of x2 is one. (Hint: Take out the Highest Common Factor as
one of the factors)
