Quadratic calculator

In algebra, a quadratic (from the Latin quadrates for "square") is an equation that will be rearranged in standard form as

ax2 + bx + c = 0

Quadradic equation

quadratic is (mathematics) a quadratic polynomial, function or equation.

Just put the values of a, b and c into the Quadratic Formula, and do the calculations.
If a=0, the equation is not quadratic.

Example: Solve \(5x^2 + 6x + c = 0\)

When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]

Coefficients are: \(a=5 . b=6 . c = 1\)
Quadratic Formula: Put in a, b and c:

\[x = {-6 \pm \sqrt{(6^2-4×5×1)} \over 2×5}.\]

\[x = {-6 \pm \sqrt{(36-20)} \over 10}.\]

\[x = {-6 \pm \sqrt{(16)} \over 10}.\]

\[x = {-6 \pm (4) \over 10}.\]

\[x = {-6 \pm 4 \over 10}.\]

\[x = -0.2 OR -1.\]

How to use the quadratic formula to solve the equation

What is the Quadrate equation?

In algebra, a quadratic (from the Latin quadrates for "square") is an equation that will be rearranged in standard form as

ax2 + bx + c = 0

Where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there's no ax2 term. The numbers a, b, and c are the coefficients of the equation and should be distinguished by calling them, respectively, the quadratic coefficient, the linear coefficient, and therefore the constant or free term.

If you'll rewrite your equation during this form, it means it is often solved with the quadratic formula. an answer to the present equation is additionally called a root of an equation.

The quadratic formula is as follows:    x = (-B ± √Δ)/2A

Where:  Δ = B² - 4AC

Using this formula, you'll find the solutions to any quadratic. Note that there are three possible options for obtaining a result:

The quadratic has two unique roots when Δ > 0. Then, the primary solution of the quadratic formula is x₁ = (-B + √Δ)/2A, and therefore the second is x₂ = (-B - √Δ)/2A.

The quadratic has just one root when Δ = 0. The answer is adequate to x = -B/2A. It’s sometimes called a repeated or double root.

The quadratic has no real solutions for Δ < 0.

You can also graph the function y = Ax² + Bx + C. Its shape may be a parabola, and therefore the roots of the quadratic are the x-intercepts of this function.

How to use the quadratic formula to solve the equation

Write down your equation. Let's assume it's 4x² + 3x - 7 = -4 - x.

Bring the equation to the shape Ax² + Bx + C = 0. During this example, we'll within the roll in the hay in the following steps:

4x² + 3x - 7 = -4 - x

4x² + (3+1)x + (-7+4) = 0

4x² + 4x - 3 = 0

Calculate the determinant.

Δ = B² - 4AC = 4² - 4*4*(-3) = 16 + 48 = 64.

Decide whether the determinant is bigger, equal, or less than 0. In our case, the determinant is bigger than 0, which suggests that this equation has two unique roots.

Calculate the 2 roots using the quadratic formula.

x₁ = (-B + √Δ)/2A = (-4 +√64) / (2*4) = (-4+8) / 8 = 4/8 = 0.5

x₂ = (-B - √Δ)/2A= (-4 -√64) / (2*4) = (-4-8) / 8 = -12/8 = -1.5

The roots of your equation are x₁ = 0.5 and x₂ = -1.5.
