x^{2} + 19 x - 18 = 4 x + 2

x = \frac{- 3 + 209}{2}

Decimal

x = 5.72841 \dots

Solution steps

x^{2} + 19 x - 18 = 4 x + 2

Square both sides:

x^{2} + 19 x - 18 = 16 x + 32

x^{2} + 19 x - 18 = 16 x + 32

Solve

x^{2} + 19 x - 18 = 16 x + 32 : x = \frac{- 3 + 209}{2}, x = \frac{- 3 - 209}{2}

x = \frac{- 3 + 209}{2}, x = \frac{- 3 - 209}{2}

Verify Solutions:

x = \frac{- 3 + 209}{2}

True

, x = \frac{- 3 - 209}{2}

False

The solution is

x = \frac{- 3 + 209}{2}

y, x + y = 8

y, x^{\frac{2}{3}} + y^{\frac{2}{3}} = 5

4 w + 4 = - 4

- 2 x^{\frac{3}{4}} + 47 = - 7

x^{\frac{1}{2}} - 3 x^{\frac{1}{4}} + 2 = 0
