The simple explanation is this: it depends on which auxiliary is being used ("avoir" or "être"). When using "être", the verb always agrees with the subject. For example: &quo...

First rearrange the equation so the LHS is equal to Zero:X²-13x-30=0Then find the factors of -30:-1,30/1,-30-2,15/2,-15-3,10/3,-10-6,5/6,-5Chose the factor pairs which add to equal -13which is ...

To solve this first we need to simplify the equation by multiplying the denominators by a common factor. If we multiply both sides of the equation by 6 we shall get an equation that is expressed with deno...

Using the chain rule, we know that dy/dx = dy/dt . dt/dx Therefore we differentiate both equations with respect to t:dx/dt = -4dy/dt = -2/(t^2)therefore dy/dx = -1/4 . -2/(t^2)dy/dx = 1/(2t^2) ... (we kno...

In French, we use the pluperfect tense when one action occurred before another action. In English, we recognise the pluperfect by "had + the past participle." For example:"She had already p...
