1/(√7) x(√7)/(√7) =(√7)/7

Let's use the following example: y - x = 3 y^2 + x^2 = 29 . Firstly, the second equation is the quadratic equation because it has a y-squared term. The first equation is linear because it doesn't have any...

We can go about solving this problem by equating the coefficients of x^2, x, and the constant c. First of all, we must expand the bracket (5x + 3)(ax + b). One helpful way of doing this correctly is the F...

Multiplying indices is much easier then it first seems. First you need to undertand what an index or power is, A^2 (A to the power of 2) means AxA, A^3 (A to the power of 3) means AxAxA and so on. The dif...
