How many real solutions can the quadratic formula give?
A quadratic equation can have either two real solutions or no real solutions.
How many real solutions does a quadratic equation have if its discriminant is negative?
The quadratic has no real solutions.
How many real solutions does a quadratic equation have if its discriminant is zero?
It will then have two equal real solutions
How many solutions are there if the discriminant of the equation is positive?
There are two distinct real solutions.
How many solution will there be if the quadratic equation does not touch or cross the x-axis?
0 real solutions. There are other solutions in the complex planes (with i, the imaginary number), but there are no real solutions.
A positive discriminant means the quadratic equation will have how many solutions?
Two distinct real solutions.
How many real solutions does the following quadratic equation have by using the discriminant?
If the discriminant > 0 then 2 distinct real solutions.If the discriminant = 0 then 1 double real solution.If the discriminant < 0 then no real solutions (though there are two complex solutions).
How many different real solutions are there for 2x2-3x plus 5 equals 0?
There are no real solutions. The discriminant (b squared -4ac) is less than 0, so there are 2 imaginary solutions and 0 real ones.
How many real solutions does a quadratic function have when the value of its discriminant is seven?
If the discriminant is positive, as in this case, there are two real solutions.Also: * If the discriminant is zero, there is one real solution, considered to be a "double solution" because of the way polynomials are factored. * If the discriminant is negative, there are two complex solutions, which are complex and non-real.
How many real solutions are there to the equqtion 4x2 plus x-1 equals 0?
It has 2 real solutions because the discriminant is greater than zero.
How many real solutions does a cubic equation have?
A cubic has from 1 to 3 real solutions. The fact that every cubic equation with real coefficients has at least 1 real solution comes from the intermediate value theorem. The discriminant of the equation tells you how many roots there are.
How many real solutions does -42 have?
None. -42 is a single integer, not an equation nor an inequality. So there are no solutions.
