Factor x2 – 3x – 28. identify the values that should be written to complete the x diagram. on the top: on the bottom: on the sides: rewrite the expression using the numbers on the sides of the x diagram. use double grouping to factor the four terms. x2 – 3x – 28 =

The factor form of given expression is .

Step-by-step explanation:

The given expression is

Therefore the factor form of given expression is .

If a expression is in the form of , then in X diagram ac is written on the top, b is written on the bottom and the required factors of ac are written on the sides.

In the given expression,

The X diagram is shown in the given figure.

Therefore the factor form of given expression is .
