2sqrt(x+4)-sqrt(x-1)=4

2 x + 4 - x - 1 = 4

x = 5, x = \frac{13}{9}

Decimal Notation

x = 5, x = 1.44444 \dots

Solution steps

2 x + 4 - x - 1 = 4

Remove square roots

9 x^{2} + 6 x + 1 = 64 x - 64

Solve

9 x^{2} + 6 x + 1 = 64 x - 64 : x = 5, x = \frac{13}{9}

x = 5, x = \frac{13}{9}

Verify Solutions:

x = 5

True

, x = \frac{13}{9}

True

The solutions are

x = 5, x = \frac{13}{9}

10 9 x = - 50

3 x = 7

\frac{5 x ^{2}}{x - 8} = 0

x = 1 0^{6}

(x^{2} + 97)^{0.5} = 10
