Question

what factoring technique will you use if the equation of a certain problem is x2-16

A. Different of two squares
B. Different of two cubes
C. Perfect square trinomial
D. General trinomial​

Answer 1

Answer:

it is c very much correct

Answer 2

Given,

Term for factorization = x²-16

To find,

The factoring technique.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

We can simply, factorise the given term, and figure out the technique eventually.

Factorization :

= x²-16

= x²-(4)²

= (x+4) (x-4)

Technique used here :

a²-b² = (a+b) (a-b)

As, LHS is difference (subtraction) of two squares (ie. a²,b²), this technique can be considered as the difference of two squares.

Hence, we will use the technique of difference of two squares.
