If the discriminant of an equation is 0?
If the discriminant of a quadratic equation is zero then it has two identical roots.
What is the discriminant in the quadratic equation x2 plus 11x plus 121 equals x plus 96?
The discriminant in the quadratic equation x2 + 11x + 121 = x + 96 is 0.Simplify the equation to the form Ax2 + Bx + C = 0 and you get x2 + 10x + 25 = 0. The discriminant is B2 - 4AC or 100 - (4)(1)(25) or 100 - 100 or 0.Not asked, but answered for completeness - since the discriminant is 0, there is one real solution, namely x = (-10 +/- 00.5) / 2 = -5
What is the discriminant of the equation -3x square - 12x plus 7 equals 8?
The equation is equivalent to: -3x2 - 12x - 1 = 0 [you could change signs to get 3x2 + 12x + 1 = 0 but that is not required] The discriminant is (-12)2 - 4*(-3)(-1) = 144 - 12 = 132
What is the discriminant of 2x2 plus 23x plus 63 equals 0?
The discriminant is 25.
How do you find the sum of the roots of the equation x2 plus 5x plus 9 equals 0?
This quadratic equation has no real roots because its discriminant is less than zero.
What is the discriminant for this equation x2-3x plus 5 equals 0?
The discriminant is -11.
In the quadratic equation ax2 plus bx plus c 0 if b2 - 4ac?
If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.
Find the value of the discriminant of each equation given X2 - 5x plus 4 equals 0?
The discriminant is 9.
What is the discriminant in the quadratic equation x 2 plus 11x plus 121 equals x plus 96?
The discriminant is 0.
What is the discriminant for x2-4x-5 equals 0?
The discriminant is 36 which means the quadratic equation has two solutions which are 5 and -1
What is the discriminant of this equation 8x2 plus 5x plus 6 equals 0?
It is: 25-4(8*6) = -167
If the discriminant of an equation is 0?
If the discriminant of a quadratic equation is zero then it has two identical roots.
What is a discriminant in a quadratic equation?
General form of a quadratic equation is: ax2+b+c = 0 The discriminant is: b2-4ac If the discriminant equals zero then there are two equal roots If the discriminant is greater than zero then there are two different roots If the discriminant is less than zero then there are no real roots
9x2-18x plus 9 equals 0 what is the discriminant?
The discriminant is 0.
What is the discriminant to determine how many real number solutions the quadratic equation -4j2 plus 3j-28 equals 0 has?
The discriminant is -439 and so there are no real solutions.
If the discriminant of a quadratic equation is -4 how many solutions does the equation have?
If the discriminant of a quadratic equation is less then 0 then it will have no real solutions.
What is the answer to x2-9x plus 21 equals 0?
This quadratic equation has no solutions because its discriminant is less than zero.
