A quadratic equation in standard form is based on the model:
ax2 + bx + c = 0
a, b, and c are called the coefficients. "Real coefficients" simply means that a, b, and c are real numbers (as opposed to complex numbers). For example:
5x2 - 3x +2 = 0
... has real coefficients, while
(3-2i)x2 + (-2 + 4i)x + (4 + 3i) = 0
does not.

How many real solutions can the quadratic formula give?
A quadratic equation can have either two real solutions or no real solutions.
What happens in the quadratic formula that yields no real solutions?
If the discriminant of b2-4ac in the quadratic equation formula is less than zero then the equation will have no real roots.
What are quadratic equations with real roots?
If the discriminant of the quadratic equation is zero then it will have 2 equal roots. If the discriminant of the quadratic equation is greater than zero then it will have 2 different roots. If the discriminant of the quadratic equation is less than zero then it will have no roots.
What are the real life application of quadratic equation in education in sustaining development?
You'll find "real-life applications" of the quadratic equation mainly in engineering applications, not in sustainable development.
A quadratic equation has how many real roots?
Quadratics can two, one or no real roots.
