Hi I'm Nick, a first year student at Durham University studying Physics. During High School I worked as a tutor for Numberworks n' Words, teaching Maths, Physics, English and even bits and pieces of Spanish! I like to focus my tutorials on exactly what the student and parents want so please keep in touch about what you need help with and I'll make sure to keep the sessions targeted and fun! Look forward to hearing from you!

### How do I find the root of a quadratic equation?

Usually the easiest way to find the root of a quadratic is to factorise it so you have something a form similar to - (x+2)(x-1)=0.

From here you need to find a value for x that makes each bracket equal to zero. Here we can see our answers are x = 1 and x = -2.

If the equation cannot be factorised our backup method that is slightly more complicated but always correct is to use the quadratic equation.

This is given as x = (-b ± (b2-4ac)1/2)/2a,

Where a, b and c come from your original quadratic as ax2+bx+c.

### When should I use the preterite and the imperfect form of the past tense?

In general the preterite is used when something has been completed. If an action has a definite start and end then you should be using the preterite, this can be both if it is something that happened once or if it is something that was repeated a specific number of times.

For example - Ayer, fue al cine. (Yesterday, he went to the cinema)

Me llamó dos veces. (He called me twice)

The imperfect is used when you don't have a definite end point. This could be something that happened generally in the past or something that has not yet been completed. It is also used often as a way of setting up the use of another past tense.

For example - Cuando era niño, tuve un fútbol. (When I was a child, I had a football)

Yo estaba hablando cuando tosía. (I was talking when he coughed)
