  • The quadratic formula to find the roots of a quadratic equation is: x 1,2 = (-b ± √Δ) / 2a where Δ = b 2 – 4ac and is called the discriminant of the quadratic equation. In our question, the equation is x 2 – 9x + 14 = 0. By remembering the form ax 2 + bx + c = 0: a = 1, b = -9, c = 14 So, we can find the discriminant first, and then ...
  • General Form. Given the following points on a parabola, find the equation of the quadratic function: (1,1); (2,4); (3,9).

Remember y and f(x) represent the same ...
  • Here h = −2 and k = 5. Answer: The vertex is (−2, 5). If there is a leading coefficient other than 1, then we must first factor out the leading coefficient from the first two terms of the trinomial. Example 13: Rewrite in y = a (x − h) 2 + k form and determine the vertex: y = 2 x 2 − 4 x + 8.

  • Example: Solve log 2 (x + 1) +log 2 (x) = 1. The first step is to use properties of logarithms to combine the logarithmic terms. Using product rule we get: log 2 ((x + 1)x) = 1 or log 2 (x 2 + x) = 1 . which is the same as. x 2 + x = 2 1 or x 2 + x - 2= 0.
