As the coefficient of x^2 is not 1, we think of this equation as ax^2 +bx + c. When the coefficient of x^2 is not 1, then we need to firstly multiply the first and last numbers together (8 and -3) which give...

One landform found near convergent boundaries are coastal fold mountains. This is through the process of subduction over billions of years. This transforms island arcs (as shown in the diagram) into continen...

y = x x , by taking logs:ln(y) = ln(x x )By log laws:ln(y) = xln(x)From implicit differentiation; d/dx = y'*d/dy, so:d/dx[ln(y)] = y'*d/dy[ln(y)] = y' * 1/yFrom the product rule; d/dx[xln(x)] = ln(x) * d/dx(...

Algebra is fundamentally the way in which we can find out the value of some unknown element. So for example, if a salesman agrees to sell two apples for £10 algebra can help us find out how much one apple wo...
