What is b2 4ac called?
the discriminant
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 b2 4ac used for?
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.
Why is it called almighty formula?
For a formula to be called Almighty, for a mathematical formula to enjoy an attribute which belongs to the Almighty, it must indeed be capable not only of solving all mathematical problems, it must also be capable of decoding and diagnosing all human problems and offer solutions to same.
What is quadratic formula used for?
This equation is known as the Quadratic Formula. This formula is very helpful for solving quadratic equations that are difficult or impossible to factor, and using it can be faster than completing the square. The Quadratic Formula can be used to solve any quadratic equation of the form ax2 + bx + c = 0.
Why b2 4ac is called the discriminant?
There is no real number whose square is negative. Therefore for this equation, there are no real number solutions. Hence, the expression (b2 – 4ac) is called the discriminant of the quadratic equation ax2 + bx + c = 0.
Who gave quadratic formula?
The 9th-century Persian mathematician Muḥammad ibn Mūsā al-Khwārizmī solved quadratic equations algebraically. The quadratic formula covering all cases was first obtained by Simon Stevin in 1594. In 1637 René Descartes published La Géométrie containing special cases of the quadratic formula in the form we know today.
What is 4ac B2 4a?
When we find the maximum value and the minimum value of ax^2 + bx + c then let us assume y = ax^2 + bx + c. Thus, the minimum value of the expression is 4ac – b^2/4a. Therefore, we clearly see that the expression y becomes maximum when a < 0. Thus, the maximum value of the expression is 4ac – b^2/4a.
What is the value of B² 4ac?
It shows the nature of the roots of any quadratic equations where a, b, and c are real numbers. Comparing the equation with the standard form. Therefore, the value of b2 – 4ac is 9.

How do you write a quadratic equation?
The standard form is ax² + bx + c = 0 with a, b and c being constants, or numerical coefficients, and x being an unknown variable.
What is the formula for discriminant?
b squared minus 4ac
The discriminant is the formula b squared minus 4ac remembering that a, b and c are the coefficients of your quadratic in standard form. It tells you the number of solutions to a quadratic equation.

Who is father of algebra?
al-Khwārizmī
al-Khwārizmī, in full Muḥammad ibn Mūsā al-Khwārizmī, (born c. 780 —died c. 850), Muslim mathematician and astronomer whose major works introduced Hindu-Arabic numerals and the concepts of algebra into European mathematics.
What is the formula of H and K?
The standard form of a quadratic function is f(x)=a(x−h)2+k. The vertex (h,k) is located at h=–b2a,k=f(h)=f(−b2a).
What is D formula?
The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equation ax2 + bx + c = 0 is D = b2 – 4ac. If D > 0, then the equation has two real distinct roots.
What is the formula of a3 b3?
a3 + b3 = (a + b) (a2 – ab + b2) (a – b)3 = a3 – b3 – 3ab (a-b)
When B² 4ac is equal to zero then the roots are?
1. If b2 – 4ac = 0 then the roots will be x = −b±02a = −b−02a, −b+02a = −b2a, −b2a. Clearly, −b2a is a real number because b and a are real. Thus, the roots of the equation ax2 + bx + c = 0 are real and equal if b2 – 4ac = 0.
