Always remember to remove any common factors as the first step, if it is possible to do so. EXAMPLE 4 Simplify. (9x-x^3)/(x^3+x^2-6x)= (x(9-x^2))/(x(x^2+x-6)) Remove a common factor from the polynomial in the numerator and in the denominator.= (x(3+x)(3-x))/(...
Finding 21/6 is equivalent to solving the equation f(x) = x6 - 2 = 0 Taking the derivative of f(x): f'(x) = 6x5 The recursion formula becomes: xn+1 = xn - ( xn6 - 2) / 6xn 5 . Using an initial guess of x1 = 1, we can generate the sequence of approximate ...

The given equation is either linear or equivalent to a linear equation. Solve the equation. \sqrt{3x} + \sqrt{12} = (x + 4)/\sqrt{3} How do you isolate a variable in a linear equation? The given equation is either linear or equivalent to a linear equation. Solve the equation. (...
In evaluating simple equations, the most basic key rule is that everything on the one side of the equation must be equivalent to everything else on the other side. Algebraic equations can be simplified by combining similar terms. Answer and Explanation: {eq}\displaystyle I_2 = 1.0 - 2I...
