Think of two small numbers __ __ Put them inside this problem: (x + __ ) (x + __ )
and multiply them out so it looks like this: x2 + __ x + __
In the form ax2 + bx + c we can say that: a = 1, b = __ and c = __
Now put the numbers a, b and c into this formula
This gives two answers: x = __ and x = __
Do they correspond to the numbers you first thought of?
Yes? Well done!
