You want to look for 12/18 in its minimal form, meaning that you cannot divide the numerator and denominator by the same number, unless that number is 1. So try to work out what the numbers are that divid...

From circle theorems, the tangent to a circle is perpendicular to the radius, and so to find the tangent we can use the gradient of the radius connecting the point (-3, -4) to the centre of the circle and...

(6² + 8²)^1/2 = (125a³ )^1/3(36+62)^1/2 = (125a³ )^1/3100^1/2 = (125a³ )^1/3+/- 10 = (125...

At the x axis, y = 0 so the equation can be made equal to zero. For a polynomial of the form ax^2 + bx + c = 0, find the value of ac. E.G ac is 2*3 = 6. Determine the two numbers which give a sum equal to...

To solve this inequality, we need to take steps to collect like terms on each side of the inequality. To start with, we can try getting all the numbers on one side of the inequality - on the left hand sid...
