Which equation(s) have -4 and 4 as solutions? Select all that apply.
A. x^2 = 8
B. x^2 + 16 = 0
C. 2x^2 = 32
D.-3x^2 = -48
E. 6x^2 + 56 = -40
F.27-5x^2 = -53

C, D, F

Step-by-step explanation:

A: 4^2=8 16=8 False

B: 4^2+16=0 16+16=- 32=0 False

C: 2(4)^2=32 - 2*8=16 True 4 squared would equal 16 as well

D: -3(4)^2=-48 -3*16=-48 True Same reasoning as C for -4

E: 6(4)^2 +56=-40 96+56=-40 False

F: 27- 5(4)^2=-53 27-5*16=-53 - 27-80=-53 -53=-53 True 4 Same reasoning as C for -4
