How to factorise algebra?
Factorising. Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3) (x - 1). This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since ...

How to factor a quadratic equation?
In quadratic equations where a = 1, factor to (x+d ) (x+e), where d × e = c and d + e = b . If your quadratic equation it is in the form x 2 + bx + c = 0 (in other words, if the coefficient of the x 2 term = 1), it's possible (but not guaranteed) that a relatively simple shortcut can be used to factor the equation. Find two numbers that both multiply to make c and add to make b. Once you find these two numbers d and e, place them in the following expression: (x+d) (x+e). These two terms, when multiplied together, produce your quadratic equation - in other words, they are your quadratic equation's factors.
How to simplify algebraic equations?
Apply the distributive property of multiplication to factor algebraic equations. Using your knowledge of how to factor both lone numbers and variables with coefficients, you can simplify simple algebraic equations by finding factors that the numbers and variables in an algebraic equation have in common. Usually, to make the equation as simple as possible, we try to search for the greatest common factor. This simplification process is possible because of the distributive property of multiplication, which states that for any numbers a, b, and c, a (b + c) = ab + ac.
How to find possible answers for a quadratic equation?
Regardless of how you factor your quadratic expression, once it is factored, you can find possible answers for the value of x by setting each factor equal to zero and solving. Since you're looking for values of x that cause your equation to equal zero, a value of x that makes either of your factors equal zero is a possible answer for your quadratic equation.
How to find a common factor of 42r and 18?
6. This number will go on the outside of the bracket so 6 (...). Then divide the original number (s) you had by 6. We end up with 7r-3.
