Answer 2

Where will the function cross the x-axis? when y = 0
how do you find when y = 0 ? factor
how do you factor
put the function in the form ax^2 + bx + c = 0
find the product of a*c including the signs
choose the factors that will add up to b watch your signs
rewrite the original with the "split" of the niddle term
group and factor

copy these steps
