x (x + 3) = 4

x = 1, x = - 4

Solution steps

x (x + 3) = 4

Expand

x (x + 3) : x^{2} + 3 x

x^{2} + 3 x = 4

Move

4

to the left side

x^{2} + 3 x - 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 1 \cdot ( - 4 )}{2 \cdot 1}

3^{2} - 4 \cdot 1 \cdot (- 4) = 5

x_{1, 2} = \frac{- 3 \pm 5}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 3 + 5}{2 \cdot 1}, x_{2} = \frac{- 3 - 5}{2 \cdot 1}

x = \frac{- 3 + 5}{2 \cdot 1} : 1

x = \frac{- 3 - 5}{2 \cdot 1} : - 4

The solutions to the quadratic equation are:

x = 1, x = - 4

x^{2} = 2.5

12 x^{2} + 72 x = 0

\frac{3 ( \frac{3}{2} ) + 2}{( \frac{3}{2} ) + 1}

- 54 x^{2} - 75 x - 24

(7 x y)^{2}
