solve the inequality x^2-4x+4>0

x2 -4x+4>0 => (x-2)(x-2)>0. We can illustrate this line on a graph showing a quadratic whose vertex is at (2,0). Therefore, the answer to our inequality is x<2,x>2 (but x does not equal 2) for all real numbers x.

P is a point on a circle with the equation x^2 + y^2 = 45. P has x-coordinate 3 and is above the x axis. Work out the equation of the tangent to the circle at point P.


Solve algebraically the simultaneous equations, x^2 + y^2 = 25 and y – 3x = 13


How do I rationalise the denominator? (Surds)


Solve this simultaneous equations, clearly showing all of your workings: x^2 + 2y =9, y - x = 3
