To find the increase in price, you have to find the change in price and then compare that to the original price. The change in price is found by doing new price-old price (£2.00-£1.50=£0.50). You then fin...

The first step is to multiply out the bracket

3x³ - 3x² - 36x = 0

Then remove the common factor 3x

3x(x² - x - 12) = 0

Then factorise the brack...

First: (x + 2)(x + 3) = x² + 5x + 6

Second: (x² + 5x + 6)(x + 6) = x³ + 5x² + 6x + 6x² + 30x + 36 = x³ + 11x² + 36x +36<...

Notice that the questions specifies that you should expand and simplify. This means expanding the equations is a good idea. To expand the equation, we will start by expanding each brackets.

3(x-2)-...

To find the answer to this, we can use the point-slope form. To do this: y - (-7) = 3 (x - 4) Simplified: y + 7 = 3x - 12 : y = 3x - 19
