You can remove parenthesis or bracket by multiplying the number outside, with the number inside the bracket.
To expand an equation you multiply the number outside the bracket with everything inside the bracket. ex. 3(x+3) becomes 3x+9
we factorise a number by finding the common factor. example: 2x+6 = 2 is the common factor the 2 is then put outside the bracket 2x+6 = 2(x+3)
It means that the term inside the brackets needs to be multiplied by the previous term outside the bracket..
the quotient

Then the answer becomes 4, the fact that you are squaring a negative number makes the result positive.

It is called a divisor. The inside number is called the dividend and the answer is the quotient. The leftover number is called the quotient but you can keep dividing until you get a decimal.

A coordinate number is two number in a bracket. Example: (4,9)
