Factor the following expression[x squared minus x minus 12]

x2-x-12

Step-by-step explanation:

Factoring a Trinomial

A trinomial is expressed in the form

Where a,b, and c are real constants.

Some trinomials can be factored as the product of binomials with real coefficients, while others cannot.

If possible, factoring can be done in several ways:

Each method is most likely applicable under certain circumstances. When the polynomial has a leading coefficient of a=1, the sum-product pattern is the fastest and easiest option.

We have the polynomial

Here: a=1, b=-1, c=-12

The sum-product method needs us to find two numbers which sum is -1 and product is -12. Those numbers can be found by inspection by combining two divisors of 12, say 1 and 12, 2 and 6, or 3 and 4.

Only one of those pairs can be combined to produce a sum or subtraction equal to -1: Those numbers are -4 and 3. Thus the factorization is:

5.5

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
