Let us take this quadratic equation as an example:2x² - 3x - 14 = 0The key here is to look for two numbers that multiply to the same number that 2 and -14 multiply to make, so that is 28. The n...

f^-1(x)= 5(x-1)

y =x/3 - 2a
y + 2a = x/3
3y+6a = x

Increase the power by one and divide by the new powere.g. integrate x²+5x + 3Answer: x³/3 + 5x²/2 + 3x

The best way to solve simultaneous equations is by substitution. The first step is to pick a variable to eliminate. In this case, I'm going to choose to eliminate y because the first equation has a y on i...
