5 x^{2} + 7 x^{2} - 25 5^{2} = 0

x = \frac{85 3}{2}, x = - \frac{85 3}{2}

Decimal Notation

x = 73.61215 \dots, x = - 73.61215 \dots

Solution steps

5 x^{2} + 7 x^{2} - 25 5^{2} = 0

Move

25 5^{2}

to the right side

5 x^{2} + 7 x^{2} = 65025

Add similar elements:

5 x^{2} + 7 x^{2} = 12 x^{2}

12 x^{2} = 65025

Divide both sides by

12

x^{2} = \frac{21675}{4}

For

x^{2} = f (a)

the solutions are

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

x = \frac{21675}{4}, x = - \frac{21675}{4}

\frac{21675}{4} = \frac{85 3}{2}

- \frac{21675}{4} = - \frac{85 3}{2}

x = \frac{85 3}{2}, x = - \frac{85 3}{2}

2 x^{2} - x - 60 = 0

y, y^{2} = \frac{x ^{3}}{2 - x}

x, (x + 3)^{2} + (y + 1)^{2} = r^{2}

4 x^{2} - 12 x = - 9

3 t (2 t - 1) = 4 t + 3
