1 - 2 x + x + 5 = 4

x = - \frac{20}{9}, x = - 4

Decimal

x = - 2.22222 \dots, x = - 4

Solution steps

1 - 2 x + x + 5 = 4

Remove square roots

9 x^{2} + 120 x + 400 = 64 x + 320

Solve

9 x^{2} + 120 x + 400 = 64 x + 320 : x = - \frac{20}{9}, x = - 4

x = - \frac{20}{9}, x = - 4

Verify Solutions:

x = - \frac{20}{9}

True

, x = - 4

True

The solutions are

x = - \frac{20}{9}, x = - 4

7 - 3 x - x = 7

x^{0.5} = 5

6 w + 7 w^{\frac{1}{2}} - 20 = 0

2 x - 3 x^{\frac{1}{2}} + 1 = 0

3 - 2 x = x
