2 a^{2} + 4 a = 6

a = 1, a = - 3

Solution steps

2 a^{2} + 4 a = 6

Move

6

to the left side

2 a^{2} + 4 a - 6 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 \cdot 2 ( - 6 )}{2 \cdot 2}

4^{2} - 4 \cdot 2 (- 6) = 8

a_{1, 2} = \frac{- 4 \pm 8}{2 \cdot 2}

Separate the solutions

a_{1} = \frac{- 4 + 8}{2 \cdot 2}, a_{2} = \frac{- 4 - 8}{2 \cdot 2}

a = \frac{- 4 + 8}{2 \cdot 2} : 1

a = \frac{- 4 - 8}{2 \cdot 2} : - 3

The solutions to the quadratic equation are:

a = 1, a = - 3

9 x^{2} + 12 x y + 4 y^{2}

2 x \cdot x

(4^{8})^{3}

x^{2} - 6 x = 7

24 x^{2} - 16 x - 39 = 0
