Exact

y = (x^2-10*x+14)/2

  1. an equation Left side of the equation is y Right side of the equation is equal to a rational expression: the top of the rational expression is a sum that contains 3 terms. The 1st term of the sum is a power. The base is x. The exponent is two. The 2nd term of the sum is equal to a negative product that consists of 2 factors. The 1st factor of the product is equal to ten. The 2nd factor of the product is equal to x. The 3rd term of the sum is fourteen. The bottom of the rational expression is two.
  2. y is x raised to the power two plus negative ten multiplied by x plus fourteen over two;


Approximate

y = 0.5*x^2-5.0*x+7.0
