Simplifying 4x2 + -3xy + -1y2 = 0 Reorder the terms: -3xy + 4x2 + -1y2 = 0 Solving -3xy + 4x2 + -1y2 = 0 Solving for variable 'x'. Factor a trinomial. (x + -1y)(4x + y) = 0
Simplifying x2 + -9xy + -36y2 = 0 Reorder the terms: -9xy + x2 + -36y2 = 0 Solving -9xy + x2 + -36y2 = 0 Solving for variable 'x'. Factor a trinomial. (x + -12y)(x + 3y) = 0
