3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
x=-.25.
Yes.
One factor is 3.
(3x-4)(x+5)
3x2=6+38=44
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
In general, no.
y2=x3+3x2
x=-.25.
No real roots.
Yes.
With difficulty because it's not an equation but an expression.

3
no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
