-14.6-(5.2) does anyone understand this

answer:  Yes ;

The answer is:  " -19.8 " .

Step-by-step explanation:

-14.6 − (5.2) =  -14.6 − 1(5.2) = ? ;

Keep the:  "(-14.6)" to the side.

and consider the:  " − 1(5.2) " ;

 Note:  The : "1" is the implied coefficient;  since:

              Any value, multiplied by "1" , results in that same value.

Since we are "subtracting", the implied coefficient is:  "-1" ["negative one"].

   So,  " - 1(5.2)"  =  -1(5.2) =  -1* 5.2 = -5.2 ;

Now, rewrite the entire problem  Bring down the:  " -14.6 " ;

 -14.6 ;  

Then, bring down the:  " -5.2" :

   -14.6 -5.2 = ? ;

 Change the "-" sign (before the "-5.2") into a "minus sign" ; and rewrite:

   -14.6 − 5.2 = ? ;

   -14.6 − 5.2 = -19.8

The answer is: " -19.8 " .

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
