sqrt(-5-7x)+sqrt(4+x)=sqrt(7-6x)

- 5 - 7 x + 4 + x = 7 - 6 x

x = - 3, x = - \frac{12}{7}

Decimal Notation

x = - 3, x = - 1.71428 \dots

Solution steps

- 5 - 7 x + 4 + x = 7 - 6 x

Remove square roots

- 80 - 132 x - 28 x^{2} = 64

Solve

- 80 - 132 x - 28 x^{2} = 64 : x = - 3, x = - \frac{12}{7}

x = - 3, x = - \frac{12}{7}

Verify Solutions:

x = - 3

True

, x = - \frac{12}{7}

True

The solutions are

x = - 3, x = - \frac{12}{7}

8 x + 17 = x + 3

b, x = \frac{- b + b ^{2} - 4 a c}{2 a}

x^{2} - 8 x + 3 x - 2 = 20 + 3 x - 2

3 x + 45 + 1 = 7
