So firstly, you need to find two numbers that multiply to make 6 and add to make 5 Make a list of numbers that multiply to make 6 i.e. 16 and 32
So you can either have (x 6)(x 1) OR...

0.5Ln(x^2+2)+ C

Explain how linear simultaneous equations with two variables ("unknowns") differ from single linear equations with two variables. Explain that a single linear equations have multiple, and indeed...

firstly, x² + 4 = 0 x² = -4 x = 2i x = -2iSecondly, x² + 8x + 25 = 0 using the quadratic formulae: x = (-b +- sqrt(b² - 4ac))/2a x = (-8+-sqrt(64-100))/2 x = -8...

To find dy/dx, the differential, of any function... you must times the coefficient of each variable of x by its power, then reduce the power by one. Using this information we can work out that 3x^4 turns ...
