x (x + 3) - 4 = 3 x + 5

x = 3, x = - 3

Solution steps

x (x + 3) - 4 = 3 x + 5

Expand

x (x + 3) - 4 : x^{2} + 3 x - 4

x^{2} + 3 x - 4 = 3 x + 5

Move

4

to the right side

x^{2} + 3 x = 3 x + 9

Move

3 x

to the left side

x^{2} = 9

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

m^{2} = 11 m

\frac{6}{11} x - 2 = \frac{5}{11} x + 3

16 a^{2} - 9 b^{2}

Y = (1)^{2}

- 5 x = 35
