Does anyone know a website that contains a logarithm calculator, a quadratic equation calculator or both? I REALLY need this. Help!!

A pretty cool equation solver I've used is at:

Log a + Log b = Log ab so log2 (x+a million) + log 2 x = log2 5 log 2 (x+a million)(x) = log2 5 x^2 + x = 5 x^2 + x - 5 = 0 x = [-a million +- sqrt (a million + 4*5) ] / 2 x = [-a million +- sqrt(21) ] / 2 now u can use the calculator to discover the marvelous value. If u want to unravel the quadratic utilising ur calculator at as quickly as, pass to the quadratic eqn. mode and a = a million, b = a million, c = -5 right here by way of fact the familiar expression is ax^2 + bx + c = 0 so u can get a, b and c by utilising evaluating ur equation with this expression.
