Step 1: Multiply the first 2 brackets(x + 1)(x + 2) =x² + x + 2x + 2 =x² + 3x + 2
Step 2: Multiply the result with the third bracket(x² + 3x + 2)(x+3)x³ + ...

1)First, let's create a table of values for x and y. For this example, let's pick values of x ranging from -2 to +4.2) We will then input our values of x into the equation, and get a corresponding value o...

When we come across questions like this, we expand by multiplying everything in the first bracket by everything in the second bracket. An easier way of doing this is rewriting the question like: x(3x+4) +...

To find the "n" in this sequence we need to calculate the difference between the terms So the result will be... n+6
