    10x^2-56=88-6x^2

    Solving for x^2:

    10x^2-56+56+6x^2=88-6x^2+56+6x^2

    16x^2=144

    Dividing both sides bt 16:

    16x^2/16=144/16

    x^2=9

    Solving for x:

    sqrt (x^2) = + - sqrt (9)

    x=+-3

    Answer: The values of x are solutions to the given equation are x = - 3 and x=3
