Divide all terms by -2:
4x2+4x+1 = 0
(2x+1)(2x+1) = 0
x = -1/2 and also x = -1/2
The quadratic equation has 2 equal roots.
no

There are an infinite number of solutions to this equation, some of which are (9,0), (12,2), (15,4), (18,6), (21,8)
6
There are an indeterminate number of invisible solutions.
no
This is an equation of a line. There are an infinite number of solutions which are all points on the line. It is a linear equation.
-2
There are an infinite number of solutions to this equation, some of which are (9,0), (12,2), (15,4), (18,6), (21,8)
is an equation of a line in plane coordinate geometry. The coordinates of every point on that line satisfy the equation so there are an infinite number of solutions to the equation.
The discriminant is -439 and so there are no real solutions.

It is not appropriate to talk about "the" three solutions for this equations; the equation describes a straight line, and has an infinite number of solutions. Solve the equation for "y", substitute any value for "x", and calculate the corresponding value for "y", to get one opf these solutions.
That equation has no solutions.There's no number that can go in place of 'x' that canmake the equation a true statement.
The number of solutions an equation has depends on the nature of the equation. A linear equation typically has one solution, a quadratic equation can have two solutions, and a cubic equation can have three solutions. However, equations can also have no solution or an infinite number of solutions depending on the specific values and relationships within the equation. It is important to analyze the equation and its characteristics to determine the number of solutions accurately.
It has one double solution.
Yes, as long as 'k' is not less than zero.
