Expressing as product of two linear expressions in brackets
ax2+bx+c=0ax^2 + bx + c = 0ax2+bx+c=0
aeq0a eq 0aeq0
bbb (coefficient of xxx)
(xquad)(xquad)=0(x quad)(x quad) = 0(xquad)(xquad)=0
Rearrange into standard form ax2+bx+c=0ax^2 + bx + c = 0ax2+bx+c=0
Expand the brackets back out
Set each bracket equal to zero
E.g., (2xquad)(xquad)(2x quad)(x quad)(2xquad)(xquad) or (3xquad)(xquad)(3x quad)(x quad)(3xquad)(xquad)
Both signs in brackets are the same
Signs in brackets are different (one +, one -)
More likely to be fractional
