It's simple. Just do the inverse.
3x squared +4=112
Take away 4 from both sides so you have 3x squared=108.
Then divide 108 by 3. This equals 36. Then find the squared root of 36. The answer is 6. =)

3x^2 + 4 = 112, 3x^2 = 108, x^2 = 36, x = 6, -6

3x squared +4=112 (-4 on both sides)
3x squared =112-4
3x squared= 108 (divide by 3)
x squared =108/3
x squared = 36
x= square root of 36
x= 6

heres how it goes: 3(xsquared)+ 4 =112. u minus 4 by 112 to get 108. you then divide 108 by 3 to get 36. if 36 = x squared, then that means a number times itself equals 36. What times itself equals 36? 6! 6 times 6 =36. 36 times 3 = 108. 108 + 4 = 112.
