To solve this question we need to find the values of x which work for the equation x^(2) + 4x + 4 = 0. To solve the equation we can factorise the left-hand side into brackets which will multiply together to ...

Let's suppose that (0+1i) 0.5 = x+iy, where x and y are both real numbers. This is the most general form of a complex number. Now let's square both sides. This gives 0+1i = x 2 +2i xy - y 2 . We will equate ...

When translating for in French, we have to take into consideration the three prepositions which can be used: d epuis, pendant and pour . The one which is selected depends on the situation and the action bein...

Curley’s wife is the only major female character in ‘Of Mice and Men’, and as such, she represents all women in Steinbeck’s novella about the futility of the American Dream. Her lack of identity outside of h...

Remember we can multiply both sides of an equation by the same thing without changing the meaning of the equation. Multiplying equation 1 by 2 gives 4x+6y=6 and multiplying equation 2 by 3 gives 9x+6y=21 . S...
