Original Equation:
(x + 2)
1/2 + (3x + 7)
1/2 = 1
Isolate one radical on the left side by subtracting the other radical from both sides of the equation:
(3x + 7)
1/2 = 1 - (x + 2)
1/2
Square both sides of the equation to get rid of radical on the left side:
3x + 7 = 1 - 2(x + 2)
1/2 + x + 2
Isolate radical on right side by subtracting (1 + x + 2) from both sides:
3x + 7 - (1 + x + 2) = -2(x + 2)
1/2
Combine like terms on left si
2x + 4 = -2(x + 2)
1/2
Square both sides of the equation to get rid of radical on right side:
4x
2 + 16x + 16 = 4(x + 2)
Distribute right side:
4x
2 + 16x + 16 = 4x + 8
Set right side to zero:
4x
2 + 16x + 16 - 4x - 8 = 0
Combine like terms on left side:
4x
2 + 12x + 8 = 0
Divide both sides by 4:
x
2 + 3x + 2 = 0
Factor left side:
(x + 2)(x + 1) = 0
Set each factor to zero and solve for x in each case:
x + 2 = 0; x + 1 = 0 x = -2; x = -1
