WebTurning Points for Quadratics. If the coefficient (the multiple) of the x 2 term is positive, then the turning point is a minimum. If negative, the turning point is a maximum. A quadratic curve is vertically symmetrical … WebA sketch of the quadratic confirms this is the correct turning point: Notice that this quadratic doesn’t have any roots (it never touches the x-axis). For this quadratic, it would have been impossible to use any method for finding the turning point that relies on knowing the roots of the quadratic (since it doesn’t have any!) The only way ...

To factor the equation, you need to first follow this equation: x^ 2 + 2ax + a^2. In x^2 +5x = 3/4, The a^2 is missing. To figure out the a, you need to take the 5 and divide it by 2 (because 2ax), which becomes 5/2. a=5/2. Then you need to square it, (because a^2) which becomes 5^2/2^2. henry reaction review
