WebOct 31, 2013 · Solving Word Problems Involving Solutions of Quadratic Functions. You can directly assign a modality to your classes and set a due date for each class. WebWhen solving quadratic equations by taking square roots, both the positive and negative square roots are solutions to the equation. This is because when we square a solution, the result is always positive. For example, for the equation x^2=4 x2 = 4, both 2 2 and -2 −2 are solutions: 2 2 = 4. 2^2\stackrel {\checkmark}=4 22 = 4.
WebSolving by factoring. Suppose we want to solve the equation x^2-3x-10=0 x2 −3x −10 = 0, then all we have to do is factor x^2-3x-10 x2 −3x −10 and solve like before! x^2-3x-10 x2 −3x −10 can be factored as (x+2) (x-5) (x +2)(x −5). [Show me the factorization.] The complete solution of the equation would go as follows: WebSolve: −200P 2 + 92,000P − 8,400,000 = 0. Step 1 Divide all terms by -200. P 2 – 460P + 42000 = 0. Step 2 Move the number term to the right side of the equation: P 2 – 460P = …
f(x) = a x 2+ b x + c If a > 0, the vertex is a minimum point and the minimum value of the quadratic function f is equal to k. This minimum value occurs at x = h. If a < 0, the vertex is a maximum point and the maximum value of the quadratic function f is equal to k. This maximum value occurs at x = h.
