Factorize the expression x(a - c) + y(c - a)
If \(y \propto \frac{1}{x^2}\) and x = 3 when y = 4, find y when x = 2.
Solve the equation 3x\(^2\) + 25x -18 = 0
Solve the equation (x +2)(x - 7) = 0
Solve the following simultaneous equations: x+ y = 3/2; x - y = 5/2 and use your result to find the value of 2y + x
