sqrt(1-2x)+sqrt(x+8)=5

1 - 2 x + x + 8 = 5

x = - 4, x = - \frac{56}{9}

Decimal Notation

x = - 4, x = - 6.22222 \dots

Solution steps

1 - 2 x + x + 8 = 5

Remove square roots

9 x^{2} + 192 x + 1024 = 100 x + 800

Solve

9 x^{2} + 192 x + 1024 = 100 x + 800 : x = - 4, x = - \frac{56}{9}

x = - 4, x = - \frac{56}{9}

Verify Solutions:

x = - 4

True

, x = - \frac{56}{9}

True

The solutions are

x = - 4, x = - \frac{56}{9}

8 t + 9 = - 9

3 - 3 x - 1 = 2 x

20 = 2 π \frac{l}{32}

2 (x - 5)^{\frac{2}{3}} = 32

- 2 x + 3 = x
