(1.2)^{2} + x^{2} = 1. 8^{2}

x = \frac{3}{5}, x = - \frac{3}{5}

Solution steps

(1.2)^{2} + x^{2} = 1. 8^{2}

Expand

1. 2^{2} + x^{2} : 1.44 + x^{2}

Expand

1. 8^{2} : 3.24

1.44 + x^{2} = 3.24

Move

1.44

to the right side

x^{2} = 1.8

For

x^{2} = f (a)

the solutions are

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

x = 1.8, x = - 1.8

1.8 = \frac{3}{5}

- 1.8 = - \frac{3}{5}

x = \frac{3}{5}, x = - \frac{3}{5}

- 3 x (x + 5) = 0

x^{2} = - 4 x - 3

2 x^{2} - 9 x - 9 = 0

6 x^{2} + 12 x

x^{2} = 2. 5^{2} + 10. 9^{2}
