When an expression is written in product form, it is said to be factored. When factored, each of the expressions being multiplied is called a factor. For example, the factored form of t - 15x + 26 is (x – 13)(x-2), so x– 13 and x-2 are each factors of the original expression.

Yes (x – 13), (x-2) are both factors of the equation.

Step-by-step explanation:

Multiplying both factors will give the original equation

factorisation is the reverse of multiplying out.

Furthermore factorization is one of the methods used to solve quadratic problems
