7 - 10 u^{2} = 1

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

Decimal Notation

u = 0.77459 \dots, u = - 0.77459 \dots

Solution steps

7 - 10 u^{2} = 1

Move

7

to the right side

- 10 u^{2} = - 6

Divide both sides by

- 10

u^{2} = \frac{3}{5}

For

x^{2} = f (a)

the solutions are

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

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

12 x^{2} - 17 x - 5 = 0

y^{2} + 8 y + 14 = 0

y, \frac{x ^{2}}{4} + \frac{y ^{2}}{9} = 1

(2 x + 5)^{2} = 0

x^{2} + 8 x - 2900 = 0
