7 x^{2} + 14 x - 16 = 8 x^{2} + 6 x

x = 4

Solution steps

7 x^{2} + 14 x - 16 = 8 x^{2} + 6 x

Move

6 x

to the left side

7 x^{2} + 8 x - 16 = 8 x^{2}

Move

8 x^{2}

to the left side

- x^{2} + 8 x - 16 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 ( - 1 ) ( - 16 )}{2 ( - 1 )}

8^{2} - 4 (- 1) (- 16) = 0

x_{1, 2} = \frac{- 8 \pm 0}{2 ( - 1 )}

x = \frac{- 8}{2 ( - 1 )}

\frac{- 8}{2 ( - 1 )} = 4

x = 4

The solution to the quadratic equation is:

x = 4

x^{2} = 0.64

x^{2} = 88

π (\frac{4}{3} + 2 n + n^{2}) = \frac{4 π}{3} + nπ

3 x (x + 7) = 0

5 x^{2} + 7 x - 50 = 4 x^{2} + 6 x + 22
