Determining a quadratic equation when given its roots
Write x=px = px=p or x=qx = qx=q
Use additive inverses: x−p=0x - p = 0x−p=0 or x−q=0x - q = 0x−q=0
Write as product: (x−p)(x−q)=0(x - p)(x - q) = 0(x−p)(x−q)=0
Signs in brackets are opposite to the given roots
Expand the brackets to get standard form
Multiple different equations can have the same roots
Multiply every term by the same non-zero constant
Multiply through to clear/eliminate the fractions
