Q(x) divided by x(x + k) is a quadratic polynomial. Biquadratic equations. A quartic equation where a 3 and a 1 are equal to 0 takes the form
The roots of the quadratic function y = 1 / 2 x 2 − 3x + 5 / 2 are the places where the graph intersects the x-axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.
Q(x) is simply the quotient obtained from the division process; since r is known to be a root of P(x), it is known that the remainder must be zero. Likewise, if several roots r, s, . . . of P(x) are known, a linear factor (x − r) can be divided out to obtain Q(x), and then (x − s) can be divided out of Q(x), etc. Alternatively, the ...
When charged particles move in electric and magnetic fields the following two laws apply: Lorentz force law: = (+),; Newton's second law of motion: = =; where F is the force applied to the ion, m is the mass of the particle, a is the acceleration, Q is the electric charge, E is the electric field, and v × B is the cross product of the ion's velocity and the magnetic flux density.
The following is known about the dimension of a finite-dimensional division algebra A over a field K: dim A = 1 if K is algebraically closed, dim A = 1, 2, 4 or 8 if K is real closed, and; If K is neither algebraically nor real closed, then there are infinitely many dimensions in which there exist division algebras over K.
Moreover, q(x) and r(x) are uniquely determined by these relations. ... If a polynomial f(x) is divided by x − k, the remainder is the constant r = f(k). [9] [10]
