A6 Quadratic equations
... Solving quadratics by completing the square Solve the equation 2x2 – 4x + 1 = 0 by completing the square. Write the answer to 3 decimal places. We can complete the square for 2x2 – 4x + 1 by first factorizing the terms containing x’s by the coefficient of x2, 2x2 – 4x + 1 = 2(x2 – 2x) + 1 Next comp ...

Intermediate Algebra Summary
... A set of ordered pairs that assign to each xvalue exactly one y-value All functions are relations, but not all relations are functions. Linear equations are always functions Read “function of x” or “f of x” f(x) is another way of writing y Any linear equation that describes a function can be written ...
