How to factor quadratic equations

Step 1: find two numbers that multiply to give ac ( in other words a x c ) and add to give b

step 2: rewrite the middle with those numbers

step 3: factor the first two and last two terms separately

step 4: if you’ve done this correctly, your two new terms should have a clearly visible common factor

and then you’re done! hope this helps!

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
