Evaluate the expression.
2’5 + 2 (12 – 7) x 4 =

Answer:

The answer would be -8.5

Step-by-step explanation:

If you start at -6.5, to find the difference (subtract) you would move left two whole spaces to get to -8.5.

On the other hand, if you were to start at 6.5 and subtract 2, your answer would be 4.5.

It depends if your first number is negative or positive.

The correct solution are:  ( − 6 ) ( − 2 ) = 12 and  ( − 6 ) ( − 6 ) = 36 .

Here it is important to remember the rules for the  addition of integers numbers:

+  +   Add  Final result (+) - Final result (+)  

-   -   Add  Final result (-) - Final result (-)  

+  -   Subtract - Final result (the sign of the integer having a greater value)

-   +  Subtract - Final result (the sign of the integer having a greater value)

The rules for multiplication of numbers are:

The result presents a positive sign (+) because the signs are the same.

  +  - or   -   +

The result presents a negative sign (-) because the signs are different.

For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.

        ( − 6 ) 2 − ( 6 ) ( 6 ) = 36

        -12 -(36) = -12 -36 = -48 -> It is not the solution given in the exercise because  -48 ≠ 36.

        ( − 6 ) ( − 2 ) =12

                12=12 -> It is the solution given in the exercise because  12=12.

      ( − 6 ) ( − 6 ) = 36

               36=36-> It is the solution given in the exercise because  36=36.

       ( − 6 ) ( − 6 ) = − 36

            36≠ -36 -> It is not the solution given in the exercise because  36 ≠ -36.

Answer:

1. The factored form of the given expression is (x+7)(x+6).

2. What is the expression in factored form . 9x^2 -4

Step-by-step explanation:

1.  The given expression is,

The degree of the expression is 2, the constant term is 42, and the coefficient of x is 13.

Use factoring by grouping method

To find the factor form, we have to find two numbers whose sum is 13 and whose product is 42.

The factors of 42 are,

From which the sum of 6 and 7 is 13.

So We can write the 13x as 7x+6x.

2. This expression can be factorized using the difference of squares which can be illustrated as follows:

A^2 - B^2 = (A+B)(A-B)

In the given example:

sqrt(9x^2) = 3x

sqrt(4) = 2

and the two squares are separated by a negative sign

Therefore, the difference of squares is applicable

Based on this, factoring the given expression would give us:

9x^2 - 4 = (3x+2)(3x-2)
