Answer:
x=7
Step-by-step explanation:
=√(x*48x + 14*48x) = 56+4x
48x^2 + 672x = (56 + 4x)^2
48x^2 + 672x = 3136 + 16x^2 + 448x
32x^2 + 224x = 3136
32x^2 + 224x - 3136 = 0
taking 32 as common we have
x^2 + 7x -98 =0
splitting the middle term
x^2 + 14x -7x -98= 0
x(x+14) -7(x+14)
(x-7) (x+13)=0
x= 7; -13
x=7
