Can y’all pls check this?

Step-by-step explanation:

1) : x = +-3

2): x=4.83 and x = -0.83

3): x= +-3.83

4): x=-8 and x =0

1st one is correct.

for second one

2(x-2)²=16

or, (x-2)² = 8

so, x = 4.83

again,

now

3x²+4=48

or, 3x² = 44

or, x² = 44/3

so, x = 3.83

again

3(x+4)²=48

or, (x+4)² = 16

or, x+4 = 4

so, x = 0

or

x+4 = -4 (since root under 16 is also -4)

x = -8
