P(x) is a polynomial. P(x) divided by (x – 8) has a remainder of 5.
P(x) divided by (x – 5) has a remainder of 3.
P(x) divided by (x + 5) has a remainder of -2.
P(x) divided by (x + 8) has a remainder of 0.

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

yes   because as the functions are graphed they eventually will intersect unless otherwise
