A polynomial with solution must be a multiple of . So, your polynomial must be a multiple of
But this is already a cubic polynomial, so it can only be a multiple in a numerical sense:
The coefficient can be found imposing the condition about the y-intercept. The y-intercept is nothing more than the polynomial evaluated at zero:
And we want this to be -12, so we have
So, your polynomial is
And if you expand it it becomes
Since it has 3 congruent sides, it must have 3 congruent angles. This triangle is an equilateral triangle. So this means that you’ll have 6x=180 and x=30
