What is the quadratic equation of 7 and 4?
What is the quadratic equation of 7 and 4?
The standard quadratic equation using the given set of solutions {−7,4} is y=x2+3x−28 y = x 2 + 3 x – 28 .
What is rational roots in quadratic equation?
The discriminant determines the nature of the roots of a quadratic equation. If Δ=0, the roots are equal and we can say that there is only one root. If Δ>0, the roots are unequal and there are two further possibilities. Δ is the square of a rational number: the roots are rational.
What is the quadratic equation of 7 and 3?

What is rational coefficient?
rational root theorem, also called rational root test, in algebra, theorem that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, the leading coefficient (the coefficient of the highest power) must be divisible by the denominator of the fraction and …
How do you find the rational numbers of a quadratic equation?
Suppose the given quadratic equation is px² + qx + r= 0, where a , b and c are rational numbers. If α and β are two roots of the above equation with α = a+√b. Now α + β = -q/p, which is rational.
What is the other root of a quadratic equation with one root?
So, the other root of a quadratic equation having the one root as (a+√b) is (a-√b), where a and b are rational numbers. , Ph.D.
Is a quadratic equation a factor of two terms?
A quadratic equation can be considered a factor of two terms. Like ax 2 + bx + c = 0 can be written as (x – x 1) (x – x 2) = 0 where x 1 and x 2 are roots of quadratic equation.
Is the constant term of a normalised quadratic constant = 1?
Yes, it is the condition as long as you are not bothered about whether the roots are real. As long as a is not 0 then the constant term of a normalised quadratic is the product of the roots, so you need c/a = 1. That is all.
