-Take factor of 5 out as seen in question.-Expand the brackets-Then draw a sketch of the graph -Then understand what type of graph it is and what it means about the line of symmetry.

A tangent line to a point of a curve is the straight line which is parallel to the the curve at that point.The equation of any straight line has equation form : y-y_1 = m(x-x_1) where m is the gradient of...

For this integration, we will use integration by substitution:First, we will let substitute u = X⁴ + 3X + 16 (this may be known as g(x) function and we will need to find the derivative of our u...

To integrate basic algebra you add one to the power of a value and then divide the coefficent by the new power, for example:To intergrate: 16x³You firstly add one to the power to get: 16...

For differentiation you simply multiply the coefficient of the unknown variable that you are differentiating by the power of the coefficient, then minus one from the power. For example to differentiate 3x...
