6-x^2=4
x^2=2
x=±sqrt(2)
(2x-4)(x-1) = 0
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
-4
-6x-4-8 = -6x -12
X equals 4
40=4-6x 40-(4)=4-6x-(4) 36=-6x -6=x
6x+4=52 6x=48 x=8
4
10
-6x
it is a combination of perfect squares the square of 9x is squared is +/- 3x, and the square of 4 is +/- 2 so the answer is (3x+2)(3x-2) which is 9xsquared-6x+6x-4 =9xsquared-4
6x-4 = 18 6x = 18+4 6x = 22 x = 22/6 = 3 and 2/3
