THIS IS REALLLY HARD ITS MATH YOU GUYS AND I DONT UNDERSTAND IT SMH LIKE BRUH jk i know what the answer is so here some points

oop thanks ig?

uhh.. ok?  thx for the points haha  i legit thought u were having a mental breakdown or something ,100% acting  XD

Step-by-step explanation:

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

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
