Solving problems involving quadratic function
WebHow To: Given a quadratic function, find the x-intercepts by rewriting in standard form.. Substitute a and b into [latex]h=-\frac{b}{2a}[/latex].; Substitute x = h into the general form … 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 … 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.
