3x - 2 = 11 3x = 13 x = 13/3 x2 + x = x( x + 1 ) = (13/3) (16/3) = 208/3 = 69-1/3
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
Yes.
One factor is 3.
(3x-4)(x+5)
2
3x2=6+38=44
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
In general, no.
y2=x3+3x2
No real roots.
Yes.
With difficulty because it's not an equation but an expression.
56
3
no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54
1 and 3
One factor is 3.
