Find the equation of the tangent to the curve y = x² -3x +5 at the point (1,3).The tangent is a straight line of the form y = mx+cTo find the gradient, m, we first differentiate the function:dy...

3x+3x-4=5,6x-4=5,6x=9,x=9/6,x=3/2

A product of prime factors is a set of prime numbers that multiply to make the requested number. Essentially, when a question asks you to express a number as a 'product of primes', it wants you to break t...

The multiplication rule is that when multiplying terms with indices, you add the indices up. In an example, if we had to simplify 3y² x 4y³ then we would first multiply the coefficie...

An easy way to find a fraction of a number is to divide by the denominator (the bottom of the fraction) and multiply by the numerator (the top of the fraction). For example, to find 3/5 of 60 we would fir...
