I will share to explain what the new coordinates will be for A' if the coordinates of A of (-2, 3) and the point is reflected across the x-axis AND I will write the algebraic rule for the problem. (make sure you explain how you came up with the new coordinates and the algebraic rule)

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

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
