3x - 4 = -2 The answer is x=2/3
(x + 2) = 3/x + 2 (x + 2)(x + 2) = 3 x + 2 = √3 x = √3 - 2 x = 1.732050808 - 2 x = -0.267949192 Check: -0.267949192 + 2 = 3/(-0.267949192 + 2) 1.732050808 = 3/1.732050808 1.732050808 = 1.732050808

Example: 30 and 42Factor them.2 x 3 x 5 = 302 x 3 x 7 = 42Select the common factors.2 x 3 = 6, the GCF
Factor them.3 x 3 x 3 = 272 x 2 x 3 x 3 = 36Select the common factors.3 x 3 = 9, the GCF
x+2=3/(x+2) (x+2)(x+2)=3 xx+4x+4=3 xx+4x+1=0 USE QUADRATIC x+2=3/x+2 x=3/x xx=3 x=sqrt(3),-sqrt(3)
3x - 4 = -2 The answer is x=2/3
(x-3)(x+2)the answer is x=3
x=-2

Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
(-x)2 = 3=> -x = ±√3=> x = -√3 and x = √3
3x - 4 = -2 The answer is x=2/3

Factor them. 2 x 2 x 2 x 3 = 24 2 x 3 x 3 x 3 = 54 Combine the factors, eliminating duplicates. 2 x 2 x 2 x 3 x 3 x 3 = 216, the LCM
(x + 2) = 3/x + 2 (x + 2)(x + 2) = 3 x + 2 = √3 x = √3 - 2 x = 1.732050808 - 2 x = -0.267949192 Check: -0.267949192 + 2 = 3/(-0.267949192 + 2) 1.732050808 = 3/1.732050808 1.732050808 = 1.732050808
3x - 4 = -2 The answer is x=2/3
