Question
For what value of a does the equation have no solution?
Solution
To find the value of a for which the equation has no solution, we need to consider the type of equation we are dealing with. If the equation is a linear equation, then it will always have a solution. However, if the equation is a quadratic equation, it may or may not have a solution depending on the discriminant.
The discriminant of a quadratic equation is given by the formula b^2 - 4ac, where a, b, and c are the coefficients of the quadratic equation in the form ax^2 + bx + c = 0.
If the discriminant is negative, then the quadratic equation has no real solutions. In other words, it has no solution in the set of real numbers. Therefore, to find the value of a for which the equation has no solution, we need to set the discriminant less than zero and solve for a.
So, the condition for the equation to have no solution is b^2 - 4ac < 0. In this case, b = 0 and c = 0, so the condition becomes -4a < 0.
Dividing both sides of the inequality by -4, we get a > 0. Therefore, the equation has no solution when a is greater than zero.
