What is √ B² 4ac 2a?
The quadratic formula is x=(-b±√(b²-4ac))/(2a). The discriminant is the part under the radical, b²-4ac. The discriminant denotes the number of real solutions.
How do you find the discriminant and nature of roots?
The discriminant is defined as Δ=b2−4ac. This is the expression under the square root in the quadratic formula. The discriminant determines the nature of the roots of a quadratic equation. The word ‘nature’ refers to the types of numbers the roots can be — namely real, rational, irrational or imaginary.
What is the discriminant of Y 2x 2 }- 3x 4y 2x 2 − 3x − 4?
The discriminant is -23.
What is the discriminant of the quadratic equation 3 4x =- 6×2?
– 56
The given quadratic equation is 3 – 4x = -6×2. The standard quadratic equation is the form ax2 + bx + c= 0. Therefore, the discriminant of the quadratic equation 3 – 4x = -6×2 is – 56.
What is the discriminant in a quadratic equation?
The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
What is the nature of roots of the quadratic equation?
We can see, the discriminant of the given quadratic equation is positive but not a perfect square. Hence, the roots of a quadratic equation are real, unequal and irrational.
Where can you find the discriminant of a quadratic equation?
What is the discriminant of the quadratic equation 0 2×2 3x 5?
49
Summary: The discriminant of the quadratic equation 2×2 + 3x – 5 = 0 is 49.
Where is the discriminant of a quadratic equation?
square root
The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
What is the value of the discriminant b2?
For the quadratic equation ax2 + bx + c = 0, the expression b2 – 4ac is called the discriminant. The value of the discriminant shows how many roots f(x) has: – If b2 – 4ac > 0 then the quadratic function has two distinct real roots. – If b2 – 4ac = 0 then the quadratic function has one repeated real root.
What is the discriminant of 76?
The discriminant is 76, which is positive. This means that there are two real solutions.
How do you find the discriminant of quadratic equations?
In quadratic equation formula, we have b2−4ac b 2 − 4 a c under root, this is discriminant of quadratic equations. There are three cases for discriminant: if b2 −4ac = 0 b 2 − 4 a c = 0, then the roots of quadratic equations are real and equal. if b2 −4ac > 0 b 2 − 4 a c > 0, then the roots are real but not equal
How do you find the number of roots of a discriminant?
A discriminant can be either positive, negative or zero. By knowing the value of a determinant, the number of roots can be determined as follows: If the discriminant value is positive, the quadratic equation has two solutions. If the discriminant value is zero, the quadratic equation has only one solution.
What does it mean if the discriminant is 0?
If the discriminant value is zero, the quadratic equation has only one solution or two real and equal solutions. If the discriminant value is negative, the quadratic equation has no real solutions. Question 1: What is the discriminant of the equation x 2 – 2x + 3 = 0?
How do you find the discriminant of a polynomial?
The discriminant of a polynomial is a function of its coefficients and represented by capital ‘D’ or Delta symbol (Δ). It shows the nature of the roots of any quadratic equation where a, b, and c are rational numbers. The real roots or the number of x-intercepts is easily shown with a quadratic equation.
