You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
Drawings in oblique projection in which the vertical plane is parallel to the plane of projection (drawing surface), and all three spatial axes are drawn to the same scale.
No.
a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.
x*2+4x+8= 0 is a quadratic equation
circulation
It is a quadratic equation that has 2 solutions
The circulatory system moves blood to the lungs. This part of the system is called the pulmonary circulation.
The blood is pushed to lungs, via pulmonary aorta. The tricuspid valve prevents the back flow into right atrium.
