negative 1 over 4

Step-by-step explanation:

C) 1 over 4.

Step-by-step explanation:

Negative 1 over 2 =

Now we have to multiply   by  

=

Remember when you multiply a negative number by a negative number, the result will be in positive. We have to multiply the numerators and the denominators.

=  

=

=

Therefore, the answer is C ) 1 over 4.

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
