The rule for differentiating a simple equation such as this is, to times the coefficient by the power and the take one away from the power. Therefore, lets look at 5x^4 you would times the 5 by 4 to get 2...
Let f be a function of a real variable into the real domain : f(x) = x^2 - 2x + 1. Find the roots and the extremum of the function f.i) Root finding The function f is a 2nd degree polynomial. The root...
b = B/2A = 8/(2x2) =8/4 = 2c = C-((B^2)/4A) = 30-((8^2)/(4x2)) = 30-64/8 = 30-8 = 22=> 2x^2 + 8x + 30 = 2(x+2)^2 + 22
2x + 5y = 11
Step 1: Rearrange one equation to make y the subject. In equation B, we can move the 3x to the other side, making it negative and making the equation y=23-3xStep 2: Substitute our new value for y into equ...
