2015年7月5日 · Get the x^2 by itself, then take square root of both sides. 27x^2-12=0 First, add 12 to both sides: 27x^2 = 12 Second, divide both sides by 27: x^2 = 12/27 Third, reduce the fraction to lowest terms: x^2 = 4/9 Fourth, take +- the square root of both sides: x=+-sqrt(4/9) Fifth, simplify the square roots: x=+-2/3 The solution set is [-2/3, 2/3]

Consider the function f(x) = – 2x3 – 27x2 – 120x on the interval [– 7,7]. Find the absolute extrema for the function on the given interval. Express your answer as an ordered pair (x, f(x)). Answer Keypad Keyboard Shortcuts Separate multiple entries with a comma. Absolute Maximum: Absolute Minimum:

Math; Calculus; Calculus questions and answers; 1 point) Consider the function f(x)=−2x3+27x2−84x+3. This function has two critical numbers A<B: A= and B= f′′(A)= f′′(B)= Thus f(x) has a local at A (type in MAX or MIN) and a local at B (type in MAX or MIN).

Find all the zeros of f(x). f(x) = 2x4 - 7x3 - 27x2 + 63x + 81 List your answers from smallest to largest. If there is a double root, list it twice. Use a comma to separate answers. Keep fractions in fractional form (no mixed fractions). For vn, use sqrt(n).
