If it helps, put the understood "1" in front of the parentheses:

. . . . .2x<sup>2</sup> - 1(4 - x<sup>2</sup>) = 6x - 4

Take the -1 through the parentheses, and simplify the left-hand side. Then move the two terms on the right over to the left. Simplify.

Then solve the quadratic by whatever method you prefer.
