56 7 x 8 products of 56, 7 is a prime factor 2 x 4 2 is a prime factor 2 x 2 Therefore, 56 as a product of its prime factors is 7 x 2 x 2 x 2 OR 7 x 2^3

(x+4)(x-2)^2(x+4)(x-2)(x-2)(x+4)(x^2-2x-2x+4)(x+4)(x^2-4x+4)x(x^2-4x+4)+4(x^2-4x+4)(x^3-4x^2+4x)+(4x^2-16x+16)x^3-12x+16

To work this out you can either work out the amount of an ingredient needed for one cake then divide the amount you have by this or you can work out how many times the amount needed for 12 cakes goes into...

Integrating the equations: x² + 4x + 3 dx. To integrate, the method is to look each parts of the equation, e.g. the x² firstly. We would add 1 to the power to get x³ . The...
