This kind of question requires correct substitution by setting the x in the original equation equal to the x value of the point ( 2k+3) and setting the y value of the original equation to the y value of t...
STEP 1: What the questions asks us is to find z that solves the equation given. Since z is a complex number, we need to determine both its real and imaginary parts. Hence, we begin by writing z in terms o...
To solve a cubic equation, you first have to guess at values for x that will solve the equation. Generally, it is good practice to start with 0, then use +/- 1, +/- 2 and so on until you find a value that...
First, we can find the slope of the line PS, with the help of the formula m = (y2- y1)/(x...
Start by expanding out the bracket on the top of the fraction to get (6x+4)/(3x2+4x+9). Then using the trick of identifying that the fraction is in the form [g(x)]/[f(x)] where f’(x)=g(x), the ...
